Re: [R] Help request: Parsing docx files for key words and appending to a spreadsheet

Hi Tim

This is brilliant - thank you!!

I've had to tweak the basePath line a bit (I am on a Linux machine), but 
having done that, the code works as intended. This is a truly helpful 
contribution that gives me ideas about how to work it through for the 
missing fields, which is one of the major sticking points I kept bumping 
up against.


Thank you so much for this.

All the best
Andy

I made a duplicate of the file you provided, so this loops through the two 
identical files, extracts a few parts,
then sticks those parts in a data frame.

#
library(textreadr)

basePath <- file.path("C:","temp")
files <- list.files(path=basePath, pattern = "docx$")

length(files)
# 2

# initialize a list to put the data in
myList <- vector(mode = "list", length = length(files))

for(i in 1:length(files)){
   fileDat <- read_docx(file.path(basePath, files[[i]]))
   # get the data you want, here one line per item to make it clearer
   # assume consistency among articles
   ttl <- fileDat[[1]]
   src <- fileDat[[2]]
   dt <- fileDat[[3]]
   aut <- fileDat[grepl("Byline:",fileDat)]
   aut <- trimws(sub("Byline:","",aut), whitespace = "[\\h\\v]")
   pg <- fileDat[grepl("Pg.",fileDat)]
   pg <- as.integer(sub(".*Pg. ([[:digit:]]+)","\\1",pg))
   len <- fileDat[grepl("Length:", fileDat)]
   len <- as.integer(sub("Length:.{1}([[:digit:]]+) .*","\\1",len))
   myList[[i]] <- data.frame("title"=ttl,
"source"=src,
"date"=dt,
"author"=aut,
"page"=pg,
"length"=len)
}

# roll up the list to a data frame. Many ways to do this.
myDF <- do.call("rbind",myList)

Hope that helps.

Hi folks

Thanks for your help and suggestions - very much appreciated.

I now have some working code, using this file I uploaded for public
access:
https://docs/.

The small code segment that now works is as follows:

###

# Load libraries
library(textreadr)
library(tcltk)
library(tidyverse)
#library(officer)
#library(stringr) #for splitting and trimming raw data
#library(tidyr) #for converting to wide format

# I'd like to keep this as it enables more control over the selected directories
filepath <- setwd(tk_choose.dir())

# The following correctly lists the names of all 9 files in my test directory 
files
<- list.files(filepath, ".docx") files
length(files)

# Ideally, I'd like to skip this step by being able to automatically read in the
name of each file, but one step at a time:
filename <- "Now they want us to charge our electric cars from litter
bins.docx"

# This produces the file content as output when run, and identifies the fields
that I want to extract.
read_docx(filename) %>%
str_split(",") %>%
unlist() %>%
str_trim()

###

What I'd like to try and accomplish next is to extract the data from selected
fields and append to a spreadsheet (Calc or Excel) under specific columns, or
if it is easier to write a CSV which I can then use later.

The fields I want to extract are illustrated with reference to the above file,
viz.:

The title: "Now they want us to charge our electric cars from litter bins"
The name of the newspaper: "Mail on Sunday (London)"
The publication date: "September 24, 2023" (in date format, preferably
separated into month and year (day is not important)) The section: "NEWS"
The page number(s): "16" (as numeric)
The length: "515" (as numeric)
The author: "Anna Mikhailova"
The subject: from the Subject section, but this is to match a value e.g.
GREENWASHING

GREENWASHING >= 50% (here this value is 51% so would be included). A 
match moves onto select the highest value under the section "Industry" 
(here it is ELECTRIC MOBILITY (91%)) and appends this text and % value. 
If no match with 'Greenwashing', then appends 'Null' and moves onto the 
next file in the directory.


###

The theory I am working with is if I can figure out how to extract these 
fields and append correctly, then the rest should just be wrapping this 
up in a for loop.


However, I am struggling to get my head around the extraction and append 
part. If I can get it to work for one of these fields, I suspect that I 
can repeat the basic syntax to extract and append the remaining fields.


Therefore, if someone can either suggest a syntax or point me to a 
useful tutorial, that would be splendid.


Thank you in anticipation.

Best wishes
Andy

Re: [R] Help request: Parsing docx files for key words and appending to a spreadsheet

[Dr Eberhard Lisse]

If you do something like this

for i in  $(pandoc --list-output-formats);
do pandoc -f docx -t $i -o test.$i Now\ they\ want\ us\ to\ 
charge\
our\ electric\ cars\ from\ litter\ bins.docx;
done

you get approximately 65 formats, from which you can pick one which you can
write a little parser for. The dokuwiki one for example uses long lines
which
makes parsing easier.

Since you're using tcltk, you can get a file path in one step using
tk_choose.files(). (Use multi = FALSE to choose only one file.)

> full_filename <- paste(filepath, filename, sep="/")

There's also file.path(), which results in slightly more compact,
self-documenting code.

Nowadays, using '/' as the directory separator can be considered
portable, one notable exception being some Windows cmd.exe built-ins
(where '/' is interpreted as flag specifier). Perl5 documentation
mentions Classic MacOS using ':' as the directory separator (and many
other operating systems supporting or emulating Unix-style '/'
separators), but that hasn't been relevant for a long while.

> Error in x$doc_obj : $ operator is invalid for atomic vectors

Which line of code produces the error? What is the argument of
docx_summary() at this point?

Since you're learning R, I can recommend a couple of free books: Visual
Statistics [1] to study the basics of R and The R Inferno [2] for when
you get stuck.

Re: [R] Help request: Parsing docx files for key words and appending to a spreadsheet

[Eric Berger]

Sorry, I was being too quick.
You have to pay attention to the pipe operator

You were advised to do the following

content <- read_docx(full_filename) |>
docx_summary()

which should have worked but I think you left out the |> operator.

Alternatively

tmp <- read_docx(full_filename)
content <-  docx_summary(tmp)

Re: [R] Help request: Parsing docx files for key words and appending to a spreadsheet

[Andy]

An update: Running this block of code:

# Load libraries
library(tcltk)
library(tidyverse)
library(officer)

filepath <- setwd(tk_choose.dir())

filename <- "Now they want us to charge our electric cars from litter 
bins.docx"

#full_filename <- paste0(filepath, filename)
full_filename <- paste(filepath, filename, sep="/")

if (!file.exists(full_filename)) {
   message("File missing")
} else {
   content <- read_docx(full_filename) |>
     docx_summary()
   # this reads docx for the full filename and
   # passes it ( |> command) to the next line
   # which summarises it.
   # the result is saved in a data frame object
   # called content which we shall show some
   # heading into from

   head(content)
}


Results in this error now:Error in x$doc_obj : $ operator is invalid for 
atomic vectors

Thank you.

docx_summary(content)

You should read documentation e.g. ?docx_summary and check the examples
section

Re: [R] Help request: Parsing docx files for key words and appending to a spreadsheet

[Andy]

Hi Eric

Thanks for that. That seems to fix one problem (the lack of a 
separator), but introduces a new one when I complete the function Calum 
proposed:Error in docx_summary() : argument "x" is missing, with no default

The whole code so far looks like this:


# Load libraries
library(tcltk)
library(tidyverse)
library(officer)

filepath <- setwd(tk_choose.dir())

filename <- "Now they want us to charge our electric cars from litter 
bins.docx"
#full_filename <- paste0(filepath, filename) # Calum's original suggestion

full_filename <- paste(filepath, filename, sep="/") # Eric's proposed fix

#lets double check the file does exist! # The rest here is Calum's 
suggestion
if (!file.exists(full_filename)) {
   message("File missing")
} else {
   content <- read_docx(full_filename)
   docx_summary()
   # this reads docx for the full filename and
   # passes it ( |> command) to the next line
   # which summarises it.
   # the result is saved in a data frame object
   # called content which we shall show some
   # heading into from

   head(content)
}


Running this, results in the error cited above.

Thanks as always :-)

Good idea, El - thanks.

This is helpful.

From the article, which is typical of Lexis+ output, I want to extract 
the following fields and append to a Calc/ Excel spreadsheet. Given the 
volume of articles I have to work through, if this can be iterative and 
semi-automatic, that would be a god send and I might be able to do some 
actual research on the articles before I reach my pensionable age. :-)


Title
Newspaper
Date
Section and page number
Length
Byline
Subject (only if the threshold of coverage for a specific subject is 
>=50% is reached (e.g. Greenwashing (51%)) - if not, enter 'nil' and 
move onto the next article in the folder


This is the ambition. I am clearly a long way short of that though.

Many thanks.

Re: [R] Help request: Parsing docx files for key words and appending to a spreadsheet

[Andy]

Thanks Ivan and Calum

I continue to appreciate your support.

Calum, I entered the code snippet you provided, and it returns 'file 
missing'. Looking at this, while the object 'full_filename' exists, what 
is happening is that the path from getwd() is being appended to the 
title of the article, but without the '/' between the end of the path 
name (here 'TEST' and the name of the article. In other words, 
full_filename is reading "~/TESTNow they want us to charge our electric 
cars from litter bins.docx", so logically, this file doesn't exist. To 
work, the '/' needs to be inserted to differentiate between the end of 
the path name and the start of the article name. I've tried both paste0, 
as you suggested, and paste but neither do the trick.

Is this a result of me using the tkinter folder selection that you 
remarked on? I wanted to keep that so that the selection is interactive, 
but if there are better ways of doing this I am open to suggestions.

Thanks again, both.

Best wishes
Andrew

Ivan thanks for spotting my fail! Since the OP is new to all this I'm going
to suggest a little tweak to this code which we can then build into a for
loop:

filepath <- getwd() #you will want to change this later. You are doing
something with tcl to pick a directory which seems rather fancy! But keep
doing it for now or set the directory here ending in a /

filename <- "Now they want us to charge our electric cars from litter
bins.docx"

full_filename <- paste0(filepath, filename)

#lets double check the file does exist!
if (!file.exists(full_filename)) {
  message("File missing")
} else {
  content <- read_docx(full_filename) |>
docx_summary()
# this reads docx for the full filename and
# passes it ( |> command) to the next line
# which summarises it.
# the result is saved in a data frame object
# called content which we shall show some
# heading into from

   head(content)
}

Let's get this bit working before we try and loop

help(read_docx) says that the function only imports one docx file. In
order to read multiple files, use a for loop or the lapply function.

A similar problem here. help(docx_summary) says that the function
accepts "rdocx" objects returned by read_docx, not file paths. A string
in R is indeed an atomic vector of type character, length 1.

docx_summary(read_docx("Now they want us to charge our electric cars
from litter bins.docx")) should work.

Re: [R] Help request: Parsing docx files for key words and appending to a spreadsheet

[Andy]

Hi Roy (& others)

Many thanks for the advice - well taken. Thanks also to the others who 
have responded so quickly - I thought I might have to wait days!! :-)

I'm on a Linux (Mint) machine. Below, I document three attempts, two 
using officer and the last now using textreadr

My attempts so far using 'officer':

##

(1) First Attempt:

# Load libraries
library(tcltk)
library(tidyverse)
library(officer)

setwd(tk_choose.dir())

doc_path <- list.files(getwd(), pattern = ".docx", full.names = TRUE)

files <- list.files(getwd(), ".docx")
files
length(files)

## This works to here - obtain a list of docx files in directory 'TEST 
with 9 files'. However, the next line
doc_in <- read_docx(files)

Results in this error:Error in filetype %in% c("docx") && 
grepl("^([fh]ttp)", file) :'length = 9' in coercion to 'logical(1)'

No idea how to debug that.

Even when trying Calum's suggestion with officer:

content <- officer::docx_summary("Now they want us to charge our 
electric cars from litter bins.docx") # A title of one of the articles

The error returned is:Error in x$doc_obj : $ operator is invalid for 
atomic vectors


##
(2) Second Attempt:

# Load libraries
library(tcltk)
library(tidyverse)
library(officer)

setwd(tk_choose.dir())

doc_path <- list.files(getwd(), pattern = ".docx", full.names = TRUE)

files <- list.files(getwd(), ".docx")
files
length(files)

docx_summary(doc_path, preserve = FALSE)
## At this point, the error is:Error in x$doc_obj : $ operator is 
invalid for atomic vectors

So, not sure how I am passing an atomic vector or if there is something 
I am supposed to set to make this something else?

##
(3) Third attempt - now trying with textreadr (Thanks for the help on 
installing this, Calum):

# Load libraries
library(tcltk)
library(tidyverse)
library(textreadr)

folder <- setwd(tk_choose.dir())

files <- list.files(folder, ".docx")
files
length(files)

doc <- read_docx("Now they want us to charge our electric cars from 
litter bins.docx") # One of the 9 files in the folder

read_docx(doc, skip = 0, remove.empty = TRUE, trim = TRUE) # To test 
against one file

## The last line returns the following error:Error in filetype %in% 
c("docx") && grepl("^([fh]ttp)", file) :'length = 38' in coercion to 
'logical(1)'

##
And so I am going around in circles and not at all clear on how I can 
make progress.

I am sure that there must be a way, but the suggestions on-line each 
lead to the above errors.

Thanks for any further help.

Best wishes, and thanks
Andy

It sounded like he looked at officeR but I would agree

content <- officer::docx_summary("filename.docx")

Would get the text content into an object called content.

That object is a data.frame so you can then manipulate it.  To be more
specific, we might need an example of the DF

You can loop this easily with a for statement although there are people who
prefer a non-for approach to iteration in R. For can be slow. But if you
don't need to do this very quickly I'd stick with for if you are used to
programming

Re: [R] Help request: Parsing docx files for key words and appending to a spreadsheet

[CALUM POLWART]

textreadr would be the obvious approach.

When you say it is depreciated do you mean it's not available on cran?
Sometimes maintaining a package on cran in just a pain in the ass.

devtools::install_github("trinker/textreadr")


Should let you install it.

In theory docx files are actually just zip files (you can unzip them) and
you may find there is then a specific file in the zip that is readable with
on of R's General text file readers.

Alternatively, read_docx from:
https://www.rdocumentation.org/packages/qdapTools

May be worth a look.

What platform are you on. Certainly options to command line convert files
to txt and do from there.

Re: [R] Help request: Parsing docx files for key words and appending to a spreadsheet

[Roy Mendelssohn - NOAA Federal via R-help]

Hi Andy:

I don’t have an answer but I do have what I hope is some friendly advice.  
Generally the more information you can provide,  the more likely you will get 
help that is useful.  In your case you say that you tried several packages and 
they didn’t do what you wanted.  Providing that code,  as well as why they 
didn’t do what you wanted (be specific)  would greatly facilitate things.

Happy new year,

-Roy

[R] Help request: Parsing docx files for key words and appending to a spreadsheet

[Andy]

Hello

I am trying to work through a problem, but feel like I've gone down a 
rabbit hole. I'd very much appreciate any help.


The task: I have several directories of multiple (some directories, up 
to 2,500+) *.docx files (newspaper articles downloaded from Lexis+) that 
I want to iterate through to append to a spreadsheet only those articles 
that satisfy a condition (i.e., a specific keyword is present for >= 50% 
coverage of the subject matter). Lexis+ has a very specific structure 
and keywords are given in the row "Subject".


I'd like to be able to accomplish the following:

(1) Append the title, the month, the author, the number of words, and 
page number(s) to a spreadsheet


(2) Read each article and extract keywords (in the docs, these are 
listed in 'Subject' section as a list of keywords with a percentage 
showing the extent to which the keyword features in the article (e.g., 
FAST FASHION (72%)) and to append the keyword and the % coverage to the 
same row in the spreadsheet. However, I want to ensure that the keyword 
coverage meets the threshold of >= 50%; if not, then pass onto the next 
article in the directory. Rinse and repeat for the entire directory.


So far, I've tried working through some Stack Overflow-based solutions, 
but most seem to use the textreadr package, which is now deprecated; 
others use either the officer or the officedown packages. However, these 
packages don't appear to do what I want the program to do, at least not 
in any of the examples I have found, nor in the vignettes and relevant 
package manuals I've looked at.


The first point is, is what I am intending to do even possible using R? 
If it is, then where do I start with this? If these docx files were 
converted to UTF-8 plain text, would that make the task easier?


I am not a confident coder, and am really only just getting my head 
around R so appreciate a steep learning curve ahead, but of course, I 
don't know what I don't know, so any pointers in the right direction 
would be a big help.


Many thanks in anticipation

Andy

Re: [R] Single pdf of all R vignettes request

[Eric Berger]

You can see all the installed vignettes on your system with
`browseVignettes()`. (This opens a browser page.)
Alternatively `browseVignettes("pkgname")` for those related to a single
package.

HTH,
Eric

Re: [R] Single pdf of all R vignettes request

[Richard O'Keefe]

Let's put some numbers on that.
The CRAN package repository claims 18770 packages.
That excludes packages in other repositories, of
course; the total collection of vignettes may not
be discoverable.
It could be useful to collect documents and vignettes
and stuff them into an information retrieval system,
but I cannot imagine a single PDF being usable.

Re: [R] Single pdf of all R vignettes request

[Jeff Newmiller]

No. It would be impractically large and would be out of date by the time it was 
finished being assembled. And not all vignettes are built in PDF form anyway.

R packages are maintained by individuals or small teams completely 
independently from R.

Re: [R] Student request for help in Self Organizing Map (SOM)

[Jeff Newmiller]

Well, this mailing list is about the R language itself, not specific packages 
or background theory. You may get an answer anyway, but you are likely to have 
better responses on the R-sig-geo mailing list or contacting the author of the 
contributed package you are using.

Also, do figure out how to configure your email program to send plain text... 
if you don't you gamble that your message (especially R code) becomes very hard 
to read after your formatting gets removed by the list.

[R] Student request for help in Self Organizing Map (SOM)

[Riaz Bibi]

Dear

I am Bibi, a PhD student of Environmental Science in South Korea.  I am
currently writing my research paper and to deal with data I need to do Self
Organizing Map (SOM).

I am using R version 4.1.0 (2021-05-18) with kohonen package.

I was following this tutorial given
http://rstudio-pubs-static.s3.amazonaws.com/437468_136a369149e24f24a4d0c152860ab4c3.html
.

But I have a small confusion that I could not understand. To check the
efficiency of SOM model, I need to find out topographic error, which I
could not figure out.

I will be really thankful if you please tell me how I can calculate
topographic error or any alternative term or which one is the topographic
error in the given article.

Please accept my apology if I wrote or mentioned something inappropriate.

Looking forward to hearing back.

Kind regards

Bibi

[R] Rserve - Request assistance with installation, confirmation thereof and starting (R 3.5.1 on 64-bit Win7 Pro)

[Rick Van Camp]

Hello,

I am attempting to install two R packages with specific version numbers.
These are Rserve_1.8-0.zip and MASS_7.3-45.zip.  As the file extension
suggests, I am installing packages from local zipfiles in the GUI Packages
menu.  R Console displays positive feedback when MASS is loaded in this
manner:

*> utils:::menuInstallLocal()*

package ‘MASS’ successfully unpacked and MD5 sums checked

The R Console does not display any message when I attempt to install Rserve
in the same manner.  What does this indicate about Rserve being installed
successfully?  I was only provided instructions to install these two
packages. No mention is made af loading them and this is feasible as Rserve
can run without R being open.

Further, I recently located two discussion threads indicating Rserve
requires a configuration file and this is created by the user.  These
threads refer the reader to three files: 1) Rserve.exe, 2) Rserve.dll, and
3) Rserve_d.exe and instructs these should be placed into the same
directory where R.dll is located (This is the bin directory on my
installation: R.home("bin")).  Next, it instructs readers to create the
file "Rserv.cfg" and provide the desired arguments such port number.

Here is my result of sessionInfo()

*> sessionInfo()*

R version 3.5.1 (2018-07-02)

Platform: x86_64-w64-mingw32/x64 (64-bit)

Running under: Windows 7 x64 (build 7601) Service Pack 1

Please let me know if you need anything else regarding my installation of

I don't know a package called "filter", but a function "filter" is in the 
"stats" package
There are however more packages to filter time data. I use "signal", which also 
has a "filter" function in addition to functions to design filters yourself 
(from simple first-order to higher-order butterworth etc).
This package is intended to filter (electrical) signals, but might be used for 
any time series.
In addition, there are several packages for the analysis of seasonal data. You 
might search CRAN for the names.
Success and
Best Wishes,


Frank

[R] Help request from Ph.D. Students

[NECMETTİN ALPAY KOÇAK]

Dear All,
I am Ph.D. student in Econometrics. My thesis is about "Linear Filtering on a 
Time Series"  which R has already a nice package, namely "Filter". This package 
is really helpful for my study. But, I really help from you to create two 
filter using with "filter" package.
I want to create two filter desribed in attachment (effects word file) using 
"filter" package. But, I dont know how?

I really need your reply,
Sincerely,

Alpay KOCAK

The "filter" package usage is given below.
filter(x, filter, method = c("convolution", "recursive"),
sides = 2, circular = FALSE, init)
And arguments,
x : a univariate or multivariate time series.
filter : a vector of filter coefficients in reverse time order (as for AR or MA 
coefficients).
method : Either "convolution" or "recursive" (and can be abbreviated). If 
"convolution" a moving average is used: if "recursive" an autoregression is 
used.
sides : for convolution filters only. If sides = 1 the filter coefficients are 
for past values only; if sides = 2 they are centred around lag 0. In this case 
the length of the filter should be odd, but if it is even, more of the filter 
is forward in time than backward.
circular : for convolution filters only. If TRUE, wrap the filter around the 
ends of the series, otherwise assume external values are missing (NA).
init : for recursive filters only. Specifies the initial values of the time 
series just prior to the start value, in reverse time order. The default is a 
set of zeros.

[R] PubChem Request Search Script

[Zsurzsa Laszlo]

Dear all,

The question would be:

   I would love to get information and match names of different chemistry
compounds. A compound looks like this.
Link: http://pubchem.ncbi.nlm.nih.gov/summary/summary.cgi?cid=2

The task is the following:

1. You input a name via R to the link, then a database searches a
similar or the same compound for you. (you autotype the name in the input
field left to the search button.)
2. parse the information that you get back. (This I can do already via
R)

Thank you for you're attention,

Re: [R] R -HELP REQUEST

[Rolf Turner]

If you just want point forecasts, it's simple:

Let your original series be X_t, t=1, ..., N.
Let Y_t = log(X_t).
Let Z_t = Y_t - Y_{t-1}, t = 2, ..., N.
Fit your model and forecast, obtaining Z-hat__1, ..., Z-hat_10.

Then Y-hat_{N+1} = Y_N + Z-hat_1, Y-hat_{N+2} = Y-hat_{N+1} + Z-hat_2,
., Y-hat_{N+10} = Y-hat_{N+9} + Z-hat_10.

In R, let your forecast values be the vector Zhat (a vector of length 10).
Then do:

Yhat - cumsum(c(Y[N],Zhat))[-1]
Xhat - exp(Yhat)

Get error bounds on the forecasts is more problematic.

Re: [R] package request

[Greg Snow]

There are packages for big data analysis, which is best depends on
what you want to do.  The High Performance Computing task view on CRAN
has a section on packages that deal with big data which gives some
more detail and may help you choose which package(s) to use.

[R] Feature request: 'file.path()' accepting an input vector

[Janko Thyson]

Dear list,

I have a small feature request regarding the implementation of 
'file.path()':


It'd be great if 'file.path()' would allow to specify an input *vector* 
instead of solely rely on a specification via the three dot argument.


AFAIU, currently it's only possible to manually specify each path 
component via the three dot argument:

 file.path(letters[1], letters[2], letters[3])
[1] a/b/c

Providing a vector object will result in the same vector being returned, 
instead of a slash separated scalar:

 file.path(letters[1:3])
[1] a b c

It'd be great if the last call would have this result:
 file.path(letters[1:3])
[1] a/b/c

If that's already possible, I'd appreciate a pointer. If not: thanks a 
lot for considering this,


Best regards,
Janko

It's not going ever to be possible: it does what it is intended and 
documented to do with a single vector, and people rely on the existing 
behaviour. OTOH


paste(x, collapse=/)

does what you want (you could use .Platform$file.sep for maximal 
portability).  Or you could use do.call(file.path, as.list(x))

Re: [R] Feature request: 'file.path()' accepting an input vector

[Janko Thyson]

Clearly you're right - and polite... as always

I asked the question because I wanted to avoid 'paste(x, collapse=/)' 
and 'do.call(file.path, as.list(x))' because it's less efficient than 
'file.path()' and '?file.path()' explicitly recommends *not* using 
'paste()' for putting together file paths.

Good day everyone, I am using the data below to fit Intervention Time Series 
model for two policies introduced in 2002 (54th data point) and 2003 (55th data 
point) respectively. Please can anyone give me a complete R code for modeling 
the two step functions? I have already modeled the pre-intervention period 
(1948 - 2001) but I need codes for the full intervention model  that estimates 
the impact parameters(omega) and the decay parameters(delta) as well. Thank you 
all for your assistance.

Hi Janko,
As Dieter said, Crantastic is an opportunity for R users to give both 
quickie ratings and reviews of packages. I have to say that doing a 
review isn't trivial. I feel that I should use a package for a while 
before I can review it, and the big packages would take quite some time 
to work through even the majority of functions, especially if you didn't 
normally use them. Nonetheless, I try to keep a running tally on the 
packages that I use, and when I've got a feeling for the capability, 
reliability and ease of use, I try to sit down and write one. I have an 
idea that many packages are downloaded and one or two useful functions 
are used a lot by any given user.


Ben's idea has been floated before, but either no one has put it 
together or I haven't heard of it. That would probably produce a lot 
more information, and the sum of a package's usage is meaningful.

[R] Feature request: rating/review system for R packages

[Janko Thyson]

Dear List,

 

I'm aware that this has been brought up before (e.g.
http://tolstoy.newcastle.edu.au/R/e6/help/09/03/7365.html
http://tolstoy.newcastle.edu.au/R/e6/help/09/03/7365.html ;
https://stat.ethz.ch/pipermail/r-help/2009-March/190902.html
https://stat.ethz.ch/pipermail/r-help/2009-March/190902.html), I couldn't
find anything recent on the topic, though.

 

After pondering all the pros and cons regarding the usefulness of a
rating/review system for R packages, don't you think it would make sense to
implement such a thing? Of course one could easily debate hours on how this
should exactly look like (quality vs. quantitiy/popularity and such), but
IMHO it would definitely be a start to have something like a simple version
Amazon's review system available. It would allow you to form at least an
initial opinion on purpose and quality of R packages before going at it. As
more and more packages pop up on CRAN, I think it'd be great to have such a
feature and that the time is ripe. 

 

Cheers,

Janko

  If I were feeling a little more ambitious, I would write a contributed

facilities built in)

  for more intrusive but complete information:

  * gave users an option to install a `hook' that would report at some
interval (regular? random?) which packages were actually loaded
(on Unix-alike machines one might be able to use the 'atime' feature
to guess when a package was *last* loaded even if it wasn't currently
in use)
  * gave users an option to contribute further information (country,
research field, etc.)
  * might pop up a window showing installed packages and offering users the
option to comment or to give ratings to particularly good or bad packages, which

where, and how it would be used; (b) carefully think about the tradeoffs
between annoying users and collecting more information; (c) consult
with the fine folks running CRANtastic to see if they wanted to somehow
integrate it into their infrastructure.

  The big advantage of this approach is that you don't need to convince
anyone from R-core to do anything, you just need to convince users to
install your package.

Re: [R] Feature request: rating/review system for R packages

[Heinz Tuechler]

It's unclear to me, why the rating/review system should relate to 
entire packages. Would it not be more informative, if single specific 
functions would be rated and reviewed?
I would like to see if + is rated better than -, or if more 
difficulties are reported for * than for /. I could then consider 
in the future to prefer sums over differences.


best,
Heinz

[R] Urgent Request

[muhammad mohsin]

Dear Colleagues,
Hope you will be fine. I am student of Ph.D and doing some work on 
distribution. 
I developed a new distribution and having some problems in estimating their 
parameters by MLE. I used R-program and  used maxLik function (maxLik: A 
Package for Maximum Likelihood Estimation in R) But there is some problem, it 
is 
not estimated the parameters properly. I also write an e-mail to the author of 
this paper but he could not solve my problem. His function works well for 
simple 
and known distribution but does not work for a new function.  Can anybody spare 
some time for me?  I really need your help. Please inform me so that I can send 
you the material.
Waiting for a quick reply

  Dear Mr Mohsin,

  You are free to post a (self-contained/reproducible and preferably
small/minimal) example here and see if it interests anyone sufficiently
for them to volunteer time to see if they can find the problem.  With respect,
though, if you are a PhD student in statistics then this is part of your
training, and it should really fall to you, or to your supervisor or other
people at your institution, to work out how to solve it. You are (much)
more likely to get useful help from this group if you can narrow 
your problem down to a specific
point, and if you can indicate what steps you have tried to take to
solve your problem for yourself.  Maximum likelihood estimation is
in general a challenging computational problem -- just because a
general-purpose function or package exists doesn't mean it can solve
all problems easily. You may have to work harder to understand 
the particular structure of your optimization problem and what 
methods will work for it.

  For a start, you might try other optimization algorithms (see e.g.
the 'optimx' package, which may be on R-forge rather than CRAN
[I don't remember], as well as the Optimization task view on CRAN).

  good luck
Ben Bolker

You could include a call to the source function that will read and run an R 
script (I have not tried this, but don't see any reason that it would not work).

[R] Help request: highlighting R code on WordPress.com blogs

[Tal Galili]

Hello dear R help members (and also Yihui and Romain),

There are currently 28 R bloggers (out of the 117
R-bloggershttp://www.r-bloggers.com/I know of) that are using
wordpress.com for publishing their R code (and I suspect this number will
increase with time).
WordPress.com doesn't support R syntax highlighting, nor can it
be embedded from other services (like gist
githttp://gettinggeneticsdone.blogspot.com/2010/09/embed-rstats-code-with-syntax.html
)

After contacting the WordPress.com vip manager, he instructed me that they
will add R support if a relevant brush will be created according to this
document:
http://alexgorbatchev.com/SyntaxHighlighter/manual/brushes/custom.html
Since this is what they use on wordpress.com (see:
http://en.support.wordpress.com/code/posting-source-code/).

Creating this brush is beyond my ability at this point, I am writing to *ask
if any of you can/wishes to make this brush *for the community.

Something I thought might be relevant is the code Yihui Xie recently
wrotehttp://yihui.name/en/2010/08/auto-completion-in-notepad-for-r-script/for
creating a NPPtoR code brush (
http://yihui.name/en/wp-content/uploads/2010/08/Npp_R_Auto_Completion.r)


If such a brush will be created, I'll push to have it included in
wordpress.com and to try and inform the current R bloggers using it.


Best,
Tal

Re: [R] Help request: highlighting R code on WordPress.com blogs

[Yihui Xie]

Thanks, Tal. It does not look too difficult to write such a brush,
which is actually a JS file. However, I have a concern that R has
thousands of functions (in base R only), so it might not worth
including all of them in the brush, which is the way that they
implemented the highlighting script for Java and VB (they didn't
define the list of functions because there are too many). Then what we
need to do is just to insert a few keywords like TRUE/FALSE/for/while
in the JS. I would like to contribute 10 minutes on this if nobody
will pick up this job.

Re: [R] Help request: highlighting R code on WordPress.com blogs

[Andrew Redd]

The question would be performance issues for having too many
functions. We could just limit it to the reserved keywords.  Another
option for the functions is to highlight anything that looks like a
function with the regular expression /[\w._]+(?=\()/  that is any
function name with periods and underscores that is immediately
followed by an open parentheses, or optionally by any number of spaces
then an open parentheses /[\w._]+[ \t]*(?=\()/

Re: [R] Feature request for as.Date() function 20)

[Greg Snow]

If you specify a format, then you don't get the error, just a missing value.  
It is a good practice to always specify the format rather than expecting the 
computer to always guess correctly or expect the original programmers to have 
anticipated everything that you may ever try. (the development version of the 
fortunes package has an entry about this).

 to feed the character string NA to the as.Date() function to yield
 the same result as `as.Date(NA)`. Please advise if testing the
 following does not yield an error:
  as.Date(NA);
 
 This may or may not aid the read.csv() error message in my particular
 code (for which a workaround has already been identified).

I have written such a function, which has provided the temporary
workaround mentioned. ( I am not that lazy yet :-) )

 R is a functional language, so write some functions.  Don't try to
 overload existing functions with new options that may break a lot of
 existing code.  If you have special requirements, then adapt your code
 to them.  You would probably have to wait around for a long time
 before an new option got in, so it is easier to create your own.

I do not mind waiting for the additional functionality (and it is no
longer an immediate need given the workaround). I was attempting to
contribute to the continued enhancement of an open source project.
Since the as.Date() function already defines standard unambiguous
formats, and since NA (and NaN, Inf, etc) are not ambiguous
within the transform to their numeric counterparts, it stands to
reason that this is logical behaviour of this function.

I also doubt this enhancement would break moderate-to-well-designed code since:
 (1) Existing code would enact a stop() condition based on the
current implementation, forcing error-handling, if any.
 (2) Converting NA (and NaN, inf, etc) is not ambiguous.
Coders feeding such strings should expect their numeric counterparts.
In all likelihood, coders would convert these strings manually in
error-handling code anyway.

I have my solution, but wanted to better the project for use by other
community members. The R Core Development Team is welcome to accept or
ignore the suggestion. I do appreciate the time to discuss this topic,
but will consider the matter closed for my part.

Thanks.

[R] A request for pointers on how to analyse Twitter with R ?

[Tal Galili]

Hello dear R members.

I just came across this website:
http://giladlotan.org/viz/iranelection/

Here what it is about:

 ReTweet Revolution is a visual exploration of the most popular conversation
 threads that were passed amongst Twitter users at the time of the events
 following the Iranian elections in June of 2009.


It uses an algorithm described here:
http://giladlotan.org/viz/iranelection/methodology.html

 A very simple rundown of my analysis process:


 1. Public Timeline Polling - During the period of the #iranelection events,
 my I would poll Twitter's public timeline, looking for keywords such as
 #iranelection,#gr88,ahmadinejad,mousavi.


 2. Text Matching Algorithm - as new tweets entered my database, making
 matches between those that belong to the same conversational thread.


 3. ReTweet analysis - mapping out the network structure by which messages
 spread between users.


 4. Text differentiation analysis - looking at syntactical differences
 between tweets from within each thread. This highlights the broken
 telephone aspect of ReTweeting, where every user can choose to change and
 add to the message as it is passed onwards.


 *more to come*



And I would love to be able to do something even similar to what he does
(simply because it is cool).

They way I see it it requires several steps into making this happen,
including:
1) a way to pull and store data from twitter
2) a way to extract the data from the database
3) tools to analyse and visualize the data (this, I imagine, can be done
using the tm package, the rest I don't know how to approach)


Can any one give interesting pointers on this one ?

Thanks,
Tal

This almost certainly means that some other email address of yours
is subscribed to the list (via which you receive the digests),
whereas the email address from which you try to post to the list
is not subscribed.

You could check this by looking into the full headers of a digest
you have received, to check what address it has been sent to. For
example, in one message to me from R-help I find (about halfway
down the list of headers):

Received: from hypatia.math.ethz.ch ([129.132.145.15]) by
 deimos.mcc.ac.uk with
 esmtps (TLSv1:AES256-SHA:256) (Exim 4.69 (FreeBSD))
 (envelope-from r-help-boun...@r-project.org)
 id 1LndwT-000A37-TR for ted.hard...@manchester.ac.uk;
 Sat, 28 Mar 2009 19:11:42 +

showing (in the for ...  clause) that the R-help list server
(hypatia.math.ethz.ch) addressed it to ted.hard...@manchester.ac.uk

If you find that out, then you could work round the problem by
using that address to post to R-help.

Alternatively, you can simply visit the R-help web page

  https://stat.ethz.ch/mailman/listinfo/r-help

and there subscribe your other email address (the one from which
you wish to post). This will then mean that you will receive the
messages from R-help at both addresses, unless yoou either use
the above web-page to disable sending of mail to one of the
addresses, or use it to unsubscribe the one you do not wish to
post from.

Though a moderator, I cannot check what addresses are subscribed
(only the list owner can do that), so that is as far as I can go
to help.

And I hope it helps!
Ted.

 Dear friends
 Hope you all are fine. Suppose we have a list of arrays.
 a1=c(4,4,4,4,0,4,4,4,0,3,3,0,0,0,0,0);  a1=array(a1,dim=c(4,4)); 
a2=c(4,4,4,

 4,0,3,3,3,3,0,4,4,4,0,0,0,0,0,0); a4=array(a4,dim=c(5,4));

 x - sapply(1:length(l), function(x) {
   sum(sapply(l, function(y) {
 if ( nrow(l[[x]]) != nrow(y) | ncol(l[[x]]) != ncol(y) ) FALSE
 else sum(y != l[[x]]) == 0
   }))
 } ); l; x
 
 Using the above function, we are able to get frequency of each most 
repeated 
 similar components of the list. For example, [[1]] and [[2]] are most 
repeated
 similar out of all. But if we consider the combinations at each row of 
each 
 array. Then [[3]] will be included with [[1]] and [[2]]. Also [[5]], 
[[6]] and
 [[8]] will be similar. How can we modify the above function to get the 
desired
 most repeated sequence in this case? Any help in this regard is needed.

 Using the above function, we are able to get frequency of each most 
repeated 
 similar components of the list. For example, [[1]] and [[2]] are most 
repeated
 similar out of all. But if we consider the combinations at each row of 
each 
 array. Then [[3]] will be included with [[1]] and [[2]]. Also [[5]], 
[[6]] and
 [[8]] will be similar. How can we modify the above function to get the 
desired
 most repeated sequence in this case? Any help in this regard is needed.

[R] Displaying number of Y/N affected by tree in rule form RE: R question/request on rules from rpart

[Sharma, Dhruv]

Hi Prof. Williams,
thanks for your suggestion.  The updated code is below.
It turns out it was a matter of displaying the second column in
yval to get the number of N and subtracting it from the n column in the
frame to get the number of Y remaining in a binary example.

once this is added now the function returns the rules along with
Y and N count affected by the resulting rule.

I am ccing the r-help post in case anyone wants to reuse this
updated version as well.

This is a great little function.  Thanks for developing it and
suggesting how to make the enhancement.

Regards,
Dhruv

Hi Dhruv,

I would think what you propose is possible, and probably even simple.
Would need to explore through the model structure. Might need to
multiply the proportions by the total to get the numbers.

 Hi Prof. Williams.
 I wanted to use your code to convert trees into rules and had a 
 question.
  
 Is there anyway to get the code below to print out the number of Y

 and N resulting by the rule?
 Currently the code prints cover=49 (0%) prob=0.91 but not the 
 number of Y or N being affected by the rule.
  
 When I plot large trees using use.n it is hard to read the numbers

 and found your rule function to be very neat.
  
 It would be great if it could be enhanced to print the number of Y

 and N affected by the rule.
  
 thanks
 Dhruv

 output is:

 Note: the obtained rows consist of all zeros should not take part in most
 repeated sequence process.

 This may come closer since it removes the zeros before comparison:

 Dear R community
 Initially i thought my problem has been solved but one thing which i found
 e.g. if
 1. All the elements of a sector are zero e.g
 , , 7

[,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10]
 [1,]0000000000
 [2,]0000000000
 [3,]0000000000
 [4,]0000000000
 [5,]0000000000

 2. Majority of the rows consist of zeros e.g.
 , , 5

[,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10]
 [1,]4400000000
 [2,]4400000000
 [3,]0000000000
 [4,]0000000000
 [5,]0000000000

 Actually
 zeros are not my values. I get values and fill the remaining parts with
 zeros like x=array(0,dim=c(3,6,5)). Now according to first strategy
 0000000000 are most repeated
 sequence of rows in both of above cases. But i don't want to consider
 cases where all elements are zeros and interested to get  44
 00000000 or just  4  4  in case 2.
 Thanks and best regards

[R] Enhancement request for bringToTop()

[Richard M. Heiberger]

Currently (R-2.7.1 on Windows)
   bringToTop(stay=TRUE)
when run before a device is opened, gives the error message
 bringToTop(stay=TRUE)
Error in bringToTop(stay = TRUE) : 
  can only bring windows devices to the front


In the same circumstances, a call to par() opens a device.

My request is to modify bringToTop().  If bringToTop()
determines that it is running in an interactive environment,
then it could open a graphics window and honor the request
to put the newly opened window on Top.

Thanks

But not necessarily a windows() device.

Only if the default graphics device were windows().  It could be Cairo(), 
for example.


bringToTop() applies to a device number, which defaults to dev.cur() which 
defaults to 1.  Unlike par() it is not confined to the current device.


You can very easily program what you seem to want.  E.g.

if(.Device == null device) windows() else bringToTop()

or perhaps

if(.Device != windows) windows() else bringToTop()

Normally opening a device brings it to the top: for Rterm users 
it might not but then bringToTop() may not either.
