Re: [R] convert microns to nm in a messy dataset
This is my approach. It is based entirely on what you said (multiply by
1000 to convert from nm to µm, but I think it is divide by). It assumes
that the starting value is in µm. If the starting value is in nm, change
the "factor=1" to "factor=1000". That µm is micro-meters (10^-6) and nm is
nano-meters (10^-9), so divide by would be correct.
factor=1;
for (i in 1:length(my.data$V19)) {
print("Start");print(factor);print(my.data[i,]);
if (my.data$V19[i] == "nm") { factor=1000;
my.data$V19[i]="µm";print("nm");} else if (my.data$V19[i] == "µm")
{factor=1;};
if (suppressWarnings(!is.na(as.numeric(my.data$V19[i] { my.data$V19[i]
= as.character(as.numeric(my.data$V19[i]) * factor); print("changed"); }
print(factor);print(my.data[i,]);print("End");

I guess your string value is in a file? And you'd like to update the file
contents. You didn't say which OS you're on. I'm a Linux person, and the
simplest for me would be:
sed -i -r "s/'/\\'/g" myfile.txt #note the \\ becomes a single \ in the
output. weird.
Or just edit the file in your favorite editor. In mine, vim, it would be
the command ":g/'/s/\\'/g" (the command is within the " marks).
You are correct that you could use gsub(). But you can't just paste your
string into an R program as is, as you have already seen. You'd need to put
it into a file. Then read that file into a program (perhaps an R program
using gsub()) to write the updated string to another file. Which contents
you could then cut'n'paste into your original R file.
something like:
#!/usr/bin/Rscript
#
files <- commandArgs(trailingOnly=TRUE);
#
for (infile in files) {
x=readLines(infile);
y=gsub("'","'",x);
ofile=paste0(infile,".new");
writeLines(y,ofile);
}

[R] MS SQL Server R Services review.
I just picked this up over on "Vulture Central" http://www.theregister.co.uk/2017/02/16/r_sql_server_great_but_beware/ The author seems both pleased and not pleased. Mainly digging at R's use (or abuse) of memory being a cause of many failures. And the fact that is is "slow" (states Python runs 17x faster) due to being interpreted. Also, to me, it seems weird to run R within the data base server itself, rather than on a client using RODBC. -- "Irrigation of the land with seawater desalinated by fusion power is ancient.

Since you are using Ubuntu, I will assume that you are using the default shell program, BASH. There is a BASH forum you could join called mailto:help-b...@gnu.org . It's easiest to sign up here: https://lists.gnu.org/mailman/listinfo/help-bash This site has some nice articles about BASH and programming (scripting) using it: http://wiki.bash-hackers.org/ BASH for beginners: http://www.tldp.org/LDP/Bash-Beginners-Guide/html/ Since you seem to be using Ubuntu: https://help.ubuntu.com/community/Beginners/BashScripting There are _TONS_ of commands installed in Ubuntu by default. Most of them have manual (man) pages. Most of the defaults are in the directory /usr/bin. You can list them simply by entering the command: "ls /usr/bin". My system has over 6,500 programs stuffed in there. If you see something interesting, you can get some basic documentation on it by using the command: "man ". We've mentioned "ls", which lists the contents of a directory. If you want to know more, try "man ls". In addition to "man" there is a much more powerful information source called "info". Just use it instead of "man" as the command name. That is, use "info ls" to get some real detailed information on the ls command. Another interesting command is "apropos". Think of it as being similar to the R systems' double question mark search. As an example, suppose you want to find out what commands might be helpful with a "zip" file. Enter the command: "apropos zip". On my system, I get a (truncated) response such as: bunzip2 (1) - a block-sorting file compressor, v1.0.6 bzip2 (1)- a block-sorting file compressor, v1.0.6 bzip2recover (1) - recovers data from damaged bzip2 files bzless (1) - file perusal filter for crt viewing of bzip2 compressed text decode (n) - Access to zip archives encode (n) - Generation of zip archives funzip (1) - filter for extracting from a ZIP archive in a pipe gunzip (1) - compress or expand files gzip (1) - compress or expand files IO::Compress::Bzip2 (3pm) - Write bzip2 files/buffers IO::Compress::Zip (3pm) - Write zip files/buffers IO::Uncompress::Unzip (3pm) - Read zip files/buffers unzip (1)- list, test and extract compressed files in a ZIP archive unzipsfx (1) - self-extracting stub for prepending to ZIP archives zforce (1) - force a '.gz' extension on all gzip files zip (1) - package and compress (archive) files zipcloak (1) - encrypt entries in a zipfile Note the number in the parentheses after the command. A "1" indicates this is a normal command. Something which starts with a "3" (like 3pm) means this is like a subroutine package (The "pm" in 3pm means "Perl Module" - like an R package, sort of). Also note that some of the entries have nothing to do with a normal "zip" file; such as the entires with bzip2 in them - bzip2 is an alternative compressor program). I'm fairly good with BASH, having programmed for over 3 decades, and used BASH for about 10 years. Which is both good and bad. The good is that I understand BASH fairly well. The bad is that I like "tricky coding" (a personal problem). > > Sarah > > -- There’s no obfuscated Perl contest because it’s pointless. —Jeff Polk Maranatha! <>< John McKown [[alternative HTML version deleted]] __ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

I'd do something like this:

You put the possible file names into the variable in the order of
preference. E.g. I prefer "dat.csv" over "dat" if by chance both exist.
> files=c('not.csv','not')
> file2read=files[file.exists(files)][1]

[1] NA
The above shows the result should none of the files exist. So if
"file2read" has an NA, then you go on to the next directory.

The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program.

Can you have the researchers input the name of the data file to be
analyzed? I use code similar to:
arguments <- commandArgs(trailingOnly=TRUE);
#
# I put in the next command due to my own ignorance
# If you invoke an R script file using just R, you
# need to say something like:
# R BATCH CMD script.R --args ... other arguments ...
#
# but if you use Rscript, you invoke it like:
# Rscript script.R ... other arguments ...
#
# Well, I got confused and did:
# Rscript script.R --args ... other arguments ...
#
# The next line adjusts for my own idiocy.
if ("--args" == arguments[1]) arguments <- arguments[-1];
#
for (file in arguments) {
...
}
Please ignore the line about my own idiocy :-}
Another thought is to use an environment variable which is set in the
user's logon profile (or the Windows registry, forgive my ignorance of
Windows). I think this would be something like:
filename <- Sys.getenv("FILENAME")
if (filename = "") {
... no file name in environment, what to do?
}
You could have someone do this for the user, if he is not familiar with
the process.

I "earned" a C- in Statistics (deserved). I don't use statistics normally. And I use R for non-statistical purposes. In particular, I use it to read files into data frames; do some minor statistical stuff (sum, mean, standard deviation, other really simple stuff); then use ggplot2 to create really nice graphs which I embed into a web page. I also use R to read a web site in order to extract data in an HTML table into an R data frame. I then do some minor manipulation and put the data into a PostgreSQL data base. I even use it to create Excel spreadsheets (for people at work who aren't wise enough to abandon it for LibreOffice). All that to say that, depending on your need, you don't need to learn statistics to be able to use R. Of course, R was designed to make it easy to do statistics. And many users here use it for that.

Did you see this from ?read.fortran
For a single-line record, ‘format’ should be a character vector.
For a multiline record it should be a list with a character vector
for each line.
I think (not sure) you need:
mydata<-read.frotran("G:/Journals/Disk1/12_restat_95/estimate/GROUPD.DAT",
list(c("1X","F6.0","5F8.6"),c("1X","5F8.4","F10.6"),c("1X","2F6.0","3E15.9","F8.0","F5.2","F5.3"),c("1X","F7.0","2E15.9","F9.4","F5.3")).

This forum doesn't handle HTML well and its use very often results in unreadable and thus unusable messages. TLI (Too Little Information). I would probably help if you would post the information from things like: dput(head(msub)) dput(head(cn)) Most want "dput(msub)" and "dput(cn)", but I use the "head()" to subset that to examples which are usually easier to post.

Looking at ?grepl, I see the option: ignore.case=TRUE
PDT2=subset(df,grepl("(.*t2.*pd.*)|(.*pd.*t2.*)",df$
Command,ignore.case=TRUE)
Perhaps this will do the trick.

The source is licensed under the GPL version 2 or 3. Commercial use: Allowed. Again ,no cost. However, as an aside, remember that R is a _interpreter_ and not a _compiler_. This means that your customers, if any, must receive the source in order to execute it. This may be a consideration. Or, if this is via a "web" site as a service, it may not. Internal use would not be any concern. Usage: Don't do evil! is about the only "usage". But, in reality, you can use it however you want within its capabilities. I wouldn't used it to do real time work, personally. If you want to use it as control software for a nuclear reactor, please tell me so I can get a dosage meter to wear. Warranty: If it breaks, you get to keep both pieces. That is, there is _no_ warranty at all. You _might_ be able to find a R consulting company which will give you some sort of contract and include some sort of warranty. But that is up to the consultant or consulting company. There is a bug reporting system _for the community_. Which means that you can report a bug, but there is no guarantee that anyone will every address it. OK, this is latter _very_ unlikely to occur because the programmers et al. behind R are conscientious, caring people. If you need a warranty, you'll need "3rd party maintenance", if there is such from anyone. Having said the above, there is no "damn it, I'm paying for support and I demand!! a fix NOW!" option (I've overhead this type of comment) .

Re: [R] Subscribe to Post
Yes. This is an _email_ group. It is not a web based discussion group. There is an "archive" of emails somewhere around, but the proper (at least IMO) way to ask a new question is to send a new email. A bit "old fashioned", but in many way it is simpler for people on many different types of computers (some of us are not Windows people!) to communicate. And, very important, be sure to post in plain text. Avoid HTML encoded email the the abomination that it is (IMO). They tend to be either ignored, or replied to in a "corrective" way (i.e. you get a nasty note back for some people). What this means in most cases is that you cannot insert an "screen print" as a "picture" (as you did in the email to which I am replying). That will get nasty-grams. And eventually many of the really good R people will just ignore you. You can not longer post via Nabble (if you did in the past). It has "abused" by way to many (the sending of HTML encoded email).

But, unfortunately, once you get into that depth, you can get into real trouble when (not if) MS decides to change the internals out from under you without any warning at all. If you are really needing this, try looking the the "MDB Tools" software at either https://github.com/brianb/mdbtools or http://mdbtools.sourceforge.net/ I don't think this does exactly what you want, but it may give you the information you need to read the MDB file yourself directly in R code. What you would really want is something like the ROWID in SQLite. That is a "system" maintained column in every table in SQLite. It is a 64-bit unique number. Basically, it starts at 1 and increments every time you add a new row.

Re: [R] exporting tables from an access database using parallel foreach
A possibility could be to not use ODBC, but the CRAN package openslsx (
https://cran.revolutionanalytics.com/web/packages/openxlsx/index.html ).
Then use the read.xlsx() function.
Description Read data from an Excel file or Workbook object into a
data.frame
Usage read.xlsx(xlsxFile, sheet = 1, startRow = 1, colNames = TRUE,
rowNames = FALSE, detectDates = FALSE, skipEmptyRows = TRUE, rows = NULL,
cols = NULL, check.names = FALSE, namedRegion = NULL)
Arguments xlsxFile An xlsx file or Workbook object sheet The name or index
of the sheet to read data from.
startRow first row to begin looking for data. Empty rows at the top of a
file are always skipped, regardless of the value of startRow.
colNames If TRUE, the first row of data will be used as column names.
rowNames If TRUE, first column of data will be used as row names.
detectDates If TRUE, attempt to recognise dates and perform conversion.
skipEmptyRows If TRUE, empty rows are skipped else empty rows after the
first row containing data will return a row of NAs.
rows A numeric vector specifying which rows in the Excel file to read. If
NULL, all rows are read.
cols A numeric vector specifying which columns in the Excel file to read.
If NULL, all columns are read.
check.names logical. If TRUE then the names of the variables in the data
frame are checked to ensure that they are syntactically valid variable
names
namedRegion A named region in the Workbook. If not NULL startRow, rows and
cols paramters are ignored.

In UNIX, I'd see if I could use just the plain "cp" command (for local, NFS, or CIFS attached places) or either the "ftp" or "scp" command to copy to a different server. In Windows the "copy" command could be used to copy the file to a different folder locally or on a "share" (Windows "share" is, more or less, the same as UNIX CIFS, if you're interested). Again, if this needs to go to some other server, then a scripted "ftp" should work.

The simplistic answer is something like:
df <- structure(list(Year = structure(1:7, .Label = c("2001", "2002",
"2003", "2004", "2005", "2006", "2007"), class = "factor"), Amount = c(150,
120, 175, 160, 120, 105, 135)), .Names = c("Year", "Amount"), row.names =
c(NA,
-7L), class = "data.frame");
wdf <- which.max(df$Amount);
adf3 <- mean(df$Amount[adf-1:adr+1]);
But that ignores the boundry condition where the maximum is at either end.
What do you want to do in that case?

Seems to be a bit off-topic. Unless your point to is to use R for
important work instead of some spreadsheet. A point with which I completely
agree!
MS-Excel, and Apache OpenOffice, appear to implement the above as
(2^2)^3==64. Whereas gnumeric implements appears to implement this as:
2^(2^3)==256. Which is "correct"? Depends on whom you ask.
ref: https://en.wikipedia.org/wiki/Order_of_operations
If exponentiation is indicated by stacked symbols, the usual rule is to
work from the top down, thus:
[image: a^{b^c} = a^{(b^c)}],
which typically is not equal to [image: (a^b)^c]. However, some computer
systems may resolve the ambiguous expression differently. For example,
Microsoft
Office Excel <https://en.wikipedia.org/wiki/Microsoft_Office_Excel>
evaluates *a*^*b*^*c* as (*a*^*b*)^*c*, which is opposite of normally
accepted convention of top-down order of execution for exponentiation. If
a=4, p=3, and q=2, [image: a^{p^q}] is evaluated to 4096 in Microsoft Excel
2013, the same as [image: (a^p)^q]. The expression [image: a^{(p^q)}], on
the other hand, results in 262144 using the same program.
Gnumeric abides by the above definition. FWIW. BTW - MS-Excel also has
1900 as a friggin' leap year (due to Lotus 1-2-3 apparently), so I don't
consider MS-Excel (or anything else from MS for that matter) to be a
definitive source of correctness. Personal opinion. FSF associate member.

I do that if there is almost any chance that I, or another, might not actually know which is first. I especially adopted this when I learned a language called APL. It has _no_ precedence of operations. And it does them from right to left. E.g. A=B*C+D is interpreted as A=B*(C+D). I did programming in it for a couple of months.

Re: [R] Running R in Server
On Sun, Aug 16, 2015 at 3:27 AM, Swagato Chatterjee swagato1...@gmail.com wrote: Hello, I have written a R script which runs a regression of a dataset and saves the result in a csv file. Now this dataset has to be edited periodically which is done in a server. I need to run the R script in a server so that the results can also be shared in a server and used in a web application. I have coded in R and have used R in windows. I have never used Ubuntu/Linux. Is there a step by step guide on how to run a R code in server? Thanks and Regards, Swagato I was going to answer yesterday, but work went insane. Also, I was hoping someone else had something, because I don't have any step by step instructions. This is a rather complicated question. So I'm going to ask a number of questions and make some statement for you to correct, if necessary. Statement: You have a Windows desktop and have used R on it, so you are familiar with R in a Windows environment. Statement: You are not Linux (Ubuntu) trained. Statement: You wrote an R script on Windows, which works, but you need to run it on Ubuntu. The above is my starting point. Now I have some questions. Can you connect to the Ubuntu server from your Windows desktop? If so, how? If not, I'm confused about how you could get anything to run on the Ubuntu server. Where does this dataset reside? On you desktop? On a Windows shared folder? On the Ubuntu server? Other? Who or what edits the dataset? That is, is it always yourself? Some one in your group? Some other human? Some automated process? Why can't you run the R script as you do now, then deploy the results to the Ubuntu server? Since I don't know the environment that the Ubuntu server runs in, I can't address how to deploy an updated file into it. I assume you have some sort of deployment software. It could be as easy as being able to ftp the results from your desktop to the proper places on the Ubuntu server. === Now, whatever the answers are to the above, you'll likely need some help from your Ubuntu server people. My first approach, given my ignorance, would be that I would have something set up so that you could edit this dataset on your desktop (assuming that's what you do). I would then have you ftp it to a special directory on the Ubuntu server set up especially for this function. Now, what remains would be running the R script, likely in a shell script (like a PowerShell command file), whenever you do the ftp. There is a function in Ubuntu (any Linux) called icrond. This is a daemon (Windows service equivalent) which can monitor a file or directory for changes. When a change is detected it can take an action. In this case it would be to schedule the execution of the previously mentioned shell script. The shell script would then take the actions necessary to do the R script (R CMD script-name parameters ... for instance) and then deploy the results to the web server (however you normally do this). Setting up the icrond environment is going to take some work by your Ubuntu administrator. === I hope this was at least the start of some help to you. -- Schrodinger's backup: The condition of any backup is unknown until a restore is attempted.

Re: [R] Common install of R on network disk
On Tue, Jul 7, 2015 at 2:42 AM, Lionel SPINELLI spine...@ciml.univ-mrs.fr
wrote:
Hello all,
I am looking for information on how to install R on a network disk so that
it can be used by several users mounting this network disk from different
computers.
We are using a cluster and shared computers in my lab. Those machines can
mount network disks. On those disks we have installed several tools, like
samtools that can be used from any user and from any machine since they
have installs that do no required any system libraries.
We would like to do the same thing with R: have a folder in the network
disk that contains R (and its libraries) and that permits to execute it
from any machine that mount the network disk. However, it seems R uses
system libraries since, once the installation done we obtain the following
message when trying to execute it from a different machine than the one
from which R was installed:
error while loading shared libraries: libicuuc.so.52: cannot open shared
object file: No such file or directory
This library seems present on the machine executing R but seems not found
the same. We did not found any info on how to set a lib path in order to
put that library with the R install.
Do you know any reference that explain how to successfully achieved the R
install as we would like to?
Thanks a lot in advance
First, I am assuming that all the clients are running the same OS at the
same, or compatible, levels. I am also assuming Linux, but that may be
pushing it. What I _think_ will work (I can't test it where I am now) is to
set the LD_LIBRARY_PATH environment to include the directory which contains
the libicuuc.so file.
For a possible example, suppose libicucc.so is in the directory
/network/disk/R-installation/lib, then try the command (I am using BASH):
LD_LIBRARY_PATH=${LD_LIBRARY_PATH}${LD_LIBRARY_PATH+:}/network/disk/R-installation/lib
R
Yes, the above is _ugly_. An easier way might be do to the following (as
root) on all the systems which want to run R (# is the command prompt for
root, not something you type in!)
# echo /netwrok/disk/R-installation/lib /etc/ld.so.conf.d/R-network.conf
# ldconfig
What the above does is add the directory /network/disk/R-installation/lib
(which contains the R shared libraries) to the directories automatically
searched for shared libraries. You can add more that one directory name,
each on a separate line, into the R-network.conf file. Oh, the name of the
file can be anything you like but must be in the directory
/etc/ld.so.conf.d and end in .conf. E.g. R-network.conf or
myIdiotBrother.conf would both work.
# echo /network/disk1/R-installation/lib
/etc/ld.so.conf.d/R-network.conf
# echo /network/disk2/R-2nd/lib /etc/ld.so.conf.d/R-network.conf
# echo /some/other/directory/entirely /etc/ld.so.conf.d/R-network.conf
# ldconfig
would add the three mentioned directories.

Also, do you know of a way to enlarge the R interface or otherwise assist in making the program accessible to a low vision person? My limited understanding leads me to believe that screen magnifiers like zoom text don't work particularly well. If you have information on that, I would very much appreciate it. Thanks for your help and for bearing with me! Courtney I am a bit confused (a normal condition for me). Is the student writing R code or is the student running a application written in R? Also, since you mentioned Excel, I am assuming that the student is using a PC running Windows as opposed to Linux or a Mac. If the student is writing R code, then I'd suggest that your computer support person install Rstudio. It is cost free and can be downloaded here: http://www.rstudio.com/ . The installer can then customize Rstudio to use a really large font, if that would be helpful. Please forgive my lack of knowledge about accessibility issues. If the student has trouble typing (mobility issue?), this likely won't help. Would a speech to text / text to speech interface help instead of a screen magnifier? I know next to nothing about these tools, other than that they exist. === If the student is running an R application (which is what enter data for her implies to me), then any accessibility issues would need to be addressed in the application itself. But I don't understand why a data entry assistant would need any skills in R itself in order to enter data into it. But without knowing more, that's about all that I can say. One thought: CMU has a college teaching electrical and computer engineering. Depending on what that means, perhaps someone from that college (professor, TA, or grad student) could see what your student is doing and perhaps have some insights on how to help. Or is there a computer club on campus where some geeky student might be found? You might look here: http://www.club.cc.cmu.edu/ If these are true geeks (and the web site sounds promising), then a lure of beer pizza would likely be irresistible grin. === For interfacing R with Excel, you might want to look at RExcel here: http://rcom.univie.ac.at/download.html#RExcel .

Re: [R] Passing strings with spaces to Python using system2 splits string at whitespace

Hi all,
I am trying to pass arguments to a python script using R, but am running
into a problem with the string being split on the white spaces.
Investigation on the python end suggests that it is happening upstream from
python, because other shells such as bash have generated similar errors.
Here is example code.
R script:
test = ./Example.py
string1 = ThisWorks
string2 = This doesn't
system2('python',args = c(as.character(test),as.character(string1))) ##
This works
system2('python',args = c(as.character(test),as.character(string2))) ##
This doesn't
use shQuote, like:
system2('python',args=shQuote(c(as.character(test),as.character(string2
Python script:
from sys import argv
script, string = argv
print script
print string
What happens is that string 2 is splits into This and doesn't. Does
anyone know how to resolve this issue? Of course I can remove the white
spaces, but that may be somewhat inconvenient.
Thanks for any help.

Re: [R] How to pass a variable to a function which use variable name as a parameter

If I understand the message correctly, it is saying that the RODBC package

have not installed it, or it is not on the library path. Perhaps the

Re: [R] the making of _R_ eBooks
On Mon, Mar 23, 2015 at 3:50 AM, Dr. Wolfgang Lindner lindn...@t-online.de wrote: Dear list members, I like the look and feel of the eBook versions of the R manuals very much. So I would like to generate eBooks (teaching material etc) in that look. I am not an expert. But I have looked at the source, so I can give you some information. Q1: is there a description how the _R_ ebooks have been produced? Looking at the source, it appears that the source manuals are in a document markup language called GNU Texinfo. https://www.gnu.org/software/texinfo/ You can think of this as something akin to, but different from, HTML or markdown encoding. Texinfo is an evolution by the system first designed by Richard Stallman of MIT. He is the driving force behind the GPL and most of the GNU software which forms the basis of the user space commands for Linux and the *BSD operating systems. Texinfo is then converted to TeX. TeX is the typesetting language designed by Dr. Donald Knuth. TeX, nominally, is converted into a DVI printer control language (DeVice Independent). But in the case of creating a PDF file, there is a processor called pdftex, http://en.wikipedia.org/wiki/PdfTeX, which produces a PDF file as output . A good site for TeX is https://tug.org/ Texinfo has the plus of also having processor which will convert it to UNIX man (manual) pages and HTML web pages. So one source document can generate three different types of output document file types. Most people use a enhanced TeX called LaTeX instead of plain TeX when using TeX. LaTeX can be read up on here: http://www.latex-project.org/ A good TeX document processor is TeXstudio at http://texstudio.sourceforge.net/ . I use this one myself (which is not necessary a strong endorsement because I'm nobody special). I feel the need to warn you that TeX is very powerful and, at least to me, quite difficult, with a fairly step learning curve. Which may be why the R project uses Texinfo because it is quite a bit easier to learn. Q2: which (free) software was used for them? See the links above. On Fedora Linux, I get the TeX oriented software from a bunch of packages which start with texlive. More information, including the processors for Linux, Windows, and Mac are at https://www.tug.org/texlive/ Q3: any other recommendations? You might consider LyX. http://www.lyx.org/ LyX is a document processor. It would likely be easier to use than the above if you are used to MS Word or other word processing system. It is cross platform: Linux, Windows, and Mac. It stores files in its own textual format, which is somewhat human readable. LyX, like Texinfo, translates its format into TeX as an intermediate on its way to its ultimate destination. I am still learning LyX, but I personally like it. Your mention of LibreOffice is also a fairly good one. I, personally, use LibreOffice. But I don't use it for big documents. I have a learned aversion for word processors because it is so easy for them to be misused. In my opinion, a good document needs good metadata in it as well as just looking pretty. Word processor users tend to focus on the format and not the content. That's just my opinion, based on what I've seen where I work. Seaching the internet gives me e.g. [1] https://sites.google.com/site/richardbyrnepdsite/ebooks-and-audiobooks/create-your-own-ebooks [2] opensource.com/life/13/8/how-create-ebook-open-source-way [3] http://scottnesbitt.net/ubuntublog/creating-a-ebook-with-libreoffice-writer/ but I m not sure, if there are better possibilities..

Re: [R] Help with Programmin-1 submission.
Gary,
First off, I doubt anyone here will really be able to help you with a
question which is, basically, How do I submit the R code that I've
worked on to my college as an answer to a programming assignment.
Unless by chance someone else here happens to be taking that course
and knows how to. It's not really an R programming question.
What I can help you with is an apparent misunderstand by you of what
source() does. source() is simply a way to say: read the lines in the
named file (not always a disk file) and act as if I had typed it all
in myself on the R command prompt.
Well, I may be chided a bit by others. But I'm bored this morning. And
I don't feel that this is actually a homework problem. So I looked
at the R code at
http://d396qusza40orc.cloudfront.net/rprog/scripts/submitscript1.R and
at your transcript. Try the following commands:
source(http://d396qusza40orc.cloudfront.net/rprog/scripts/submitscript1.R;)
setwd('H:/RStudio-Projects/Project1/')
submit()
Note that I replaced the second source() with a setwd() command. The
first source() defines some R programs for you. The setwd() makes your
current working directory be H:/RStudio-Projects/Project1/ which I
guess is where pollutantmean.R resides. The submit() function looks
for a __FILE__ in the __current working directory__ for the code which
you want to submit to your instructor. From what I can see, the
submit() process itself does the required source() to run your R code,
but only from your __current working directory__ (yes, I'm emphasizing
that). The rest of what you did after the submit() command looks to
match what the submit() function was wanting.
Now, I will emphasize yet again that this question is totally outside
the purview of this forum. Your question should have been asked of
your teacher, or a TA, or (as we were called back when I was in
college) a user's ass (we weren't P.C,. or even polite, back in the
60s. I had to help people with key punch machines and card readers). I
only went into this because: (1) I'm bored and (2) you look like you
might be just a bit younger that me and I believe in helping kids
succeed grin.

Re: [R] regex find anything which is not a number
See if the following will work for you:
grep('^-?[0-9]+([.]?[0-9]+)?$',myvector,perl=TRUE,invert=TRUE)
myvector - c(a3, N.A, 1.2, -3, 3-2, 2.)
grep('^-?[0-9]+([.][0-9]+)?$',myvector,perl=TRUE,invert=TRUE)
[1] 1 2 5 6
The key is to match a number, and then invert the TRUE / FALSE (invert=TRUE).
^ == start of string
-? == 0 or 1 minus signs
[0-9]+ == one or more digits
optionally followed by the following via use of (...)?
[.] == an actual period. I tried to escape this, but it failed
[0-9]+ == followed by one or more digits
$ == followed by the end of the string.
so: optional minus, followed by one or more digits, optionally
followed by (a period with one or more ending digits).

So far I am able to detect anything which is not a number, excluding - and .

I still need to capture positions 5 and 6, which in human language

If you read it and only see 3 terminators, you might think R is the same, but it's not. R sees that as 7 different statements: two on the 1st, 2nd and 4th lines (in each case the second statement is empty), and one statement on line 3. So verylongname ends up with the value 3, not 4.

There is one possible problem with your solution. Consider the string:
arhofixednorhofixed. It ends with norhofixed and, according to the original
specification, needs to result in arhofixed. (I will admit this is a
contrived case which is very unlikely to occur in reality). But since you
do TWO regular expressions, first removing the trailing norhofixed,
resulting in arhofixed (the correct answer?), but then reduces that to
simply a. The other regular expressions correctly remove either
norhofixed or rhofixed, if they are written _correctly_. That is, they
check first for norhofixed, with an alternate of rhofixed, or conditionally
match the no in front of the rhofixed at the very end of the string (my
example). To be even more explicit the regexp nohrofixed|rhofixed will
work properly but rhofixed|norhofixed will not because the norhofixed
won't be looked for if the rhofixed matches. Yes, regular expressions can
be complicated. Although I have a liking for them due to their
expressiveness and power, it is like an person using raw nitroglycerin

So I thought that it might be of interest to some others here. https://medium.com/the-physics-arxiv-blog/cause-and-effect-the-revolutionary-new-statistical-test-that-can-tease-them-apart-ed84a988e http://arxiv.org/abs/1412.3773 Title: Distinguishing cause from effect using observational data: methods and benchmarks quote The discovery of causal relationships from purely observational data is a fundamental problem in science. The most elementary form of such a causal discovery problem is to decide whether X causes Y or, alternatively, Y causes X, given joint observations of two variables X, Y . This was often considered to be impossible. Nevertheless, several approaches for addressing this bivariate causal discovery problem were proposed recently. In this paper, we present the benchmark data set CauseEffectPairs that consists of 88 different cause-effect pairs selected from 31 datasets from various domains. We evaluated the performance of several bivariate causal discovery methods on these real-world benchmark data and on artificially simulated data. Our empirical results provide evidence that additive-noise methods are indeed able to distinguish cause from effect using only purely observational data. In addition, we prove consistency of the additive-noise method proposed by Hoyer et al.

Of course, there are factorial(28) (about 3*10^29 ) such 4x7 matrices.

I think it would be 1/168th ( 1 out of 7*factorial(4) ) of the 3*10^29 permutations, or about 1.8*10^27. Which is still way to big to actually instantiate all at once.

It's simply hide the error.

Dear useRs,I have been wondering whether it would be possible to fit a
linear mixed model including heteroscedastic variances for a 2-level
hierarchical study with subsampling.Suppose that I had three levels for the
first hierarchical level and 4 for the second, with 2 subsamples, e.g.
set.seed(2014)y - rnorm(24, 20, 2)level1 - gl(3, 8)level2 - gl(4,
2)my.data - data.frame(y, level1, level2)
Then, I can easily fit a model with nested random effects, i.e.
y_{ijk} = \mu + \alpha_i + \beta_{ij} + \epsilon_{ijk}
with \alpha_i ~ N(0, \sigma^2_1) the random effect for level 1, \beta_{ij}
~ N(0, \sigma^2_2) the random effect for level 2 and \epsilon_{ijk} ~ N(0,
sigma^2) the error,
using the following code
require(nlme)fit1 - lme(y ~ 1, random=~1|level1/level2, my.data)
# which is equivalent tofit1 - lme(y ~ 1, random=list(level1=pdDiag(~1),
level2=pdDiag(~1)), my.data)
However, I would like to have different variances per each level1 level
(model i) and then a different model considering different variances per
each level1 and per each level2 level within level1 (model ii).So we
would have
Model (i):\alpha_i ~ N(0, \sigma^2_1_i), \beta_{ij} ~ N(0, \sigma^2_2) and
\epsilon_{ijk} ~ N(0, sigma^2),
that is, different sigma^2_1 per level1 level
Model (ii):\alpha_i ~ N(0, \sigma^2_1_i), \beta_{ij} ~ N(0,
\sigma^2_2_{ij}) and \epsilon_{ijk} ~ N(0, sigma^2),
that is, different sigma^2_1 per level1 level and different sigma^2_2
per level1:level2 level combination
I tried the following for model (i):
fit2 - lme(y ~ 1, random=list(level1=pdDiag(~level1)), my.data)
and this for model (ii):
fit3 - lme(y ~ 1, random=list(level1=pdDiag(~level1),
level2=pdDiag(~level1:level2)), my.data)
This second fit also gives a warning, and I don't believe that these are
doing what I intend to.I also tried using the weights argument, i.e., for
model (i)
fit2.2 - lme(y ~ 1, random=~1|level1/level2,
weights=varIdent(form=~1|level1), my.data)
Perhaps this is closer to what I'm trying to do, but when it comes to
model (ii) I can't properly work the syntax, as the / creates an error,
so I tried
fit2.3 - lme(y ~ 1, random=~1|level1/level2,
weights=varIdent(form=~1|level1*level2), my.data)
but I'm still doubtful.
Any suggestions on how I might be able to fit these models?
Best wishes,Rafael.

What occurs to me, from reading the other replies, is that perhaps within the loop you are causing other objects to be allocated.

That's where you allocate a big chunk of memory for an object. Say this take up 1/2 of your available space. You now create a small object. This object is _probably_ right next to the large object. You now release the large object. Your apparent free space is now almost what it was at the beginning. But when you try to allocate another large object which is, say, 2/3 of the maximum space, you can't because that small object is sitting right in the middle of our memory space. So you _can_ allocate 2 large objects which are 1/3 your free space size, but not 1 object which is 2/3 of the free space size. Which can lead to your type of situation.

AT and at are not the same. If you want an case insensitive compare for the characters at you need the ignore.case=TRUE added. E.g.: df[,grep(.at,colnames(df),ignore.case=TRUE) That should match the column name you gave. Which does not match your initial description which said ending with .at. That has an embedded AT.

Re: [R] grep won't work finding one column
You're right. I don't use regexps in R very much. In most other languages, a single \ is needed. The R parser is different and I forgot. Thanks for the heads up.

Re: [R] Changing date format

Dear All,
The following function gives me what I wanted.
The input of function is one value and this push me to use sapply function
to call it.
Is there a better way of doing this?
#
day - function(x){
if(x== 60) {
y = 29 Feb
}
if(x 60){
y = format(strptime(x, format = %j), format =%d-%b)
}
if(x 60){
y = format(strptime(x - 1, format = %j), format =%d-%b)
}
y
}
sapply(Samaru$Start,day)
[1] 17-Apr 27-Apr 24-Apr 04-Jun 25-Apr 13-May 22-Apr
05-May 27-Apr 13-May 27-Apr
#===
I make no comment about whether the above is correct or you, because
I don't know. There is much that I don't know. There is a way to
reformulate the function in a way that I personally think is better.
You might want to look at:
day - function(x) { ifelse(x==60,29
Feb,format(strptime(x-(x60),format=%j),format=%d-%b)); }
The trick is that x-(x60) will subtract 1 from x when x is greater
than 60, but 0 if it is less than or equal to 60. And the ifelse takes
care of the case where x is equal to 60. As I said, I don't know that
this really gives you want, but it is functionally equivalent to the
code you posted. However, it is not as obvious. As we say about the
lottery: You pay your money, you take your chance.

In these cases, the E is stripped so I get just 055 or 020. The question is how should this data be imported to avoid the E-ending problem?

Re: [R] How can I create colors correspond to the number of a variable?
First off, please post in plain text not HTML. It is a forum requirement. HTML posts are often ignored, especially if they look messy in plain text, which is all that the mailing list software distributes. It strips off the HTML portion entirely. Your question is vague in that you didn't indicate what you wanted in the way of colors and what you were going to do with them. For plotting? For visually distinguishing one out of 4,000 possible beds by color on a screen display? If you want plotting, then use ggplot2 and the scale_color_brewer() function: http://docs.ggplot2.org/current/scale_brewer.html . My personal opinion is that it is unlikely that an average person will be able to memorize 4,000 different colors, be able to see one of them, and say definitively that is bed number ---. Especially if the person is even mildly color blind. Depending on use, the U.S. ADA (American with Disabilities Act) may become a factor. Companies need to remember this. Individuals, not so much. But rather than give any real opinion about this question, I will just point out some archive messages which might be of some help. https://groups.google.com/forum/#!searchin/r-help-archive/$2Br-help$20$2Bcolor/r-help-archive/yOXrLIU-S8M/jc0yRQ6tNZgJ https://groups.google.com/forum/#!searchin/r-help-archive/$2Br-help$20$2Bcolor/r-help-archive/duLEBjtqzTU/J45x_EB2BAIJ This doesn't address R, but does address the use of color, and gives a reference to the R color brewer (http://colorbrewer2.org/) http://ux.stackexchange.com/questions/17964/how-many-visually-distinct-colors-can-accurately-be-associated-with-a-separate Pantone, an industry standard in color, has 2,058 colors in their Goe inventory: http://pantone.custhelp.com/app/answers/detail/a_id/1671/related/1 This site might help you select the colors: http://www.colorsontheweb.com/ And I do know that I did not directly answer your question with a piece of code.
