Re: [R] Getting Started

[Dalthorp, Daniel]

By "contribute", do you mean you have a package (or potential package) that
you'd like to share? Or do you have something else in mind?

Re: [R] Getting Started

[Bert Gunter]

You obviously know little about R or you would not have asked that
question. So heeding Jim's advice is clearly your first step. A second
would be to read the "Writing R extensions" manual to learn about R
packages. A third would be to check out the CRAN task views to get a sense
of what's available in the 3000 or more packages users have already
contributed.

Cheers,

Bert

Re: [R] Getting Started

[Jim Lemon]

Hi Lakshya,
One good way to contribute is to try to do something in R, and if you
see a way to do it better or more easily, you may have an improvement
that will find its way into R. This usually involves a lot of
discovering that someone else has already done it, but as your
knowledge of R expands, so do the opportunities to find something that
no one has yet accomplished.

Jim

 Hi Ben -- in your code from this morning you had a function

 fitting - function(ndx.grd=two,dt.grd=**one,ind.vr='ind',rsp.vr='res') {
 ## ... setup
 for(i in 1:length(ndx.grd[,1])){
 ## ... do work
 }
 ## ... collate results
 }

 that you're trying to run in parallel. Obviously the ## ... represent
 lines I've removed. When you say something like

 y - foreach(icount(length(two))) %dopar% fitting()

 its saying that you want to run fitting() length(two) times. So you're
 actually doing the same thing length(two) times, whereas you really want to
 divide the work thats inside fitting() into chunks, and do those on
 separate cores!

 Conceptually what you'd like to do is

 fit_one - function(idx, ndx.grd, dt.grd, ind.vr, rsp.vr) {
 ## ... do work on row idx _ONLY_
 }

 and then evaluate with

 ## ... setup
 y -
   foreach (idx = icount(nrow(two)) %dopar% one_fit(idx, two, one, ind,
 res)
 ## ... collate

 so that fit_one fits just one of your combinations. foreach will worry
 about distributing the work. Make sure that fit_one works first, before
 trying to run this in parallel; your use of try(), trying to fit different
 data types (character, integer, numeric) into a matrix rather than
 data.frame, and the type coercions all indicate that you're fighting with R
 rather than working with it.

 Hope that helps,

 Martin

[R] getting started with R and mysql

[Michael Friendly]

I have a mysql database I installed on my Ubuntu server, and I'm trying 
to figure out how to access and analyze it

from a Win XP machine running R 2.15.1.

I thought that RMySQL was the way to go. (Is there an easier way?) I 
tried to follow the instructions at

http://www.r-bloggers.com/installing-the-rmysql-package-on-windows-7/
so I installed mysql-installer-community-5.5.27.0.msi, then set the 
environment variable MYSQL_HOME,
and tried to install RMySQL within R. It failed, as shown below, but I 
can't see what is wrong.
What's missing? If I only want to read tables from the database and work 
on them in R, is there an

easier package?

From Windows, RODBC is likely to be easier, not least as binaries are 
available.  You will need to install the ODBC driver of the appropriate 
(32- or 64-bit) architecture.


A while ago the tricky steps were to get the Unix-alike server to allow 
access from elsewhere.  This may have changed (because we have serious 
MySQL database servers, I now leave this to my sysadmins).

[R] Getting started with Bayesian Change Point model in R

[Kendra Karr]

Hi- I am interested in running the BCP model in R and I am also new to R.

My main issue is how to ask a specific questions within the script for 
this model,
i.e., how one or multiple dependent factors (blue) are interact with the 
dependent factor (yellow), and nest the question do categorical factors 
(green) changes those interactions.  I have attached some fake data in 
the link below with potential results. Thanks for any script or 
suggestions on how to develop this model further.

Once those questions have been completed I am interested tweaking the 
model to prioritize the data (observations) based upon frequency of 
observations in space and time, then run the initial questions again.

http://research.pbsci.ucsc.edu/eeb/kendrakarr/bcp/

Well thanks for any thoughts!

[R] Getting started

[Andrew Kelly]

Hi,)
I am just getting started with R but have hit an early snag. I am working 
through Crawley (2008) The R Book and on page 6, 'Significance Stars', I am 
trying to enter the commands given. However, 'Gain.txt' does not seem to have 
been downloaded when I downloaded the R programme.

I have searched for it in case it put it somewhere other than 'temp' but I 
cannot find it.

Can anybody tell me how to do this?

Many thanks

Re: [R] Getting Started with Bayesian MCMC

[Greg Snow]

The purpose of the task view is to answer questions like this.  I for one would 
not be able to give a better answer than what is there.

My suggestion would be to pull out your Bayesian textbook (or get one, or use 
online notes from a class, etc.) and look through the homework problems and 
examples for things that may be similar to what you may be doing in the future. 
 Then try doing those problems/examples using a few of the different tools 
recommended in the task view (start with simple things even if they are not the 
types of problems you will do for real, just to get a feel for the different 
packages).  This will help you decide which packages work best for you and 
which interfaces you prefer.  Then when you have real problems to solve, you 
will have the knowledge of which tools to use and how to use them.

You should also consider contributing what you learn back to the task view for 
others.

Hi Ben,

Before you begin playing with BUGS/JAGS, there are several native R
packages that deal with a wide variety of Bayesian models that worth
considering. Among many others, I find MCMCpack, DPpackage, and
MCMCglmm very useful (and convenient).

Best,

[R] Getting started,

[gug]

Hello,

First of all, I'm new to R and I don't have anyone who already knows the
language to ask for tips, so please excuse my ignorance.

I'm trying to download data direct from the Federal Reserve statistics
website and graph it, using the following:

#This downloads the data from the Fed website
download.file(http://www.federalreserve.gov/releases/h15/data/Business_day/H15_ED_M1.txt,Eurodollar_deposits1M.dat;)

#This reads that data into a table
data_download=read.table(Eurodollar_deposits1M.dat,skip=8,sep=,,head=T)

#This is attempting to get R to read the date column, which is in
mm/dd/ format
#I have restricted it to the first 50 data points (to keep it simple)
date_vec = as.Date(data_download[1:50,1],%m/%d/%y)

#This reads the values again for just the first 50 data points
eurodollar_vec = data_download[1:50,2]

#This plots the date and data values.
plot(date_vec,eurodollar_vec)


A few issues with the output from this:

1) The date_vec data ends up looking like this 2019-01-04 - for some
reason all year 2019, irrespective of the actual year (e.g. 1971, 1972). 
Any suggestions as to where I am going wrong?

2) The chart ends up as a scatter diagram, not surprisingly.  I initially
tried to use the ts.plot() function but when I did, I found that it doesn't
use the date column in the data as the x axis.  Is there a way of creating a
time series that uses the date column, or alternatively, how would I turn
these two columns (date  value) into a line graph?

3) The y-axis output should be from about 4.5 to about 8.5, but the y-axis
shows as being about 430-670.  There also seems to be a line of points
across the top which are all of the same value - as though anything above
about 670 gets charted as 670.


I'm sorry for this being a what am I doing wrong post, but I have looked
through the manuals without success, and I am new enough to R that I don't
have a feel for ways round these sorts of problems.  Any suggestions would
be greatly appreciated.  Thanks.

Re: [R] Getting started,

[jim holtman]

In answer to your first question, your statement should be:

date_vec = as.Date(data_download[1:50,1],%m/%d/%Y)

Notice the capital Y; lower case says the year is only 2 digits, so
you were pickup up the '19' from the date.

Use 'plot(..., type='l')' for a line plot.

Your data is being read in as factors:

 str(data_download)
'data.frame':   9972 obs. of  2 variables:
 $ DATE: Factor w/ 9972 levels 01/01/1973,01/01/1974,..: 84 112
140 167 195 279 307 335 362 390 ...
 $ EDM1: Factor w/ 673 levels  0.70, 0.75,..: 599 597 593 594 591
586 583 571 574 586 ...

You need to convert EDM1 to numeric

data_download$EDM1 - as.numeric(as.character(data_download$EDM1))

and then your data will plot as you like.

Re: [R] Getting started help

Thank you very much, everybody. The scale of responses of depth of guidance
is overwhelming. All this will help me to become an expert in no time! I
have a while yet as I am still collecting data for my PhD project but when I
start statistical data analysis, thanks to all of you, I will know what to
do with one of the required softwares!

I will let you know how I get on.

Re: [R] Getting started help

[Mark Difford]

Hi Rthoughts,

 I am currently discouraged by the use of r. I cannot figure out how to
 use it despite
 extensive searches. Can anyone help me with getting started? How can
 import 
 a txt file with series...

There are piles of documents that you could (and should) read.  I am
surprised that you haven't found them in your extensive searches.  To set
your thoughts free, go here:

http://www.r-project.org/
http://cran.r-project.org/manuals.html## read the first one, and
whatever else you need

Then click on CRAN, and choose a mirror site (nearby), say:
http://cran.za.r-project.org/

Then go:
http://cran.za.r-project.org/other-docs.html

and start at the top.

HTH,
Mark.

PS: It might help you in your future enquiries if you used a real name, and
if you called R R rather than r (since your keyboard clearly doesn't have a
broken R ;).

Re: [R] Getting started help

[My Coyne]

Hi Rthoughts,

Don't be discouraged I'm learning R on/off for classes and when I was
under pressure to get work done, learning R likes pulling my hair (and
teeth) off of frustration.  But, this forum is great; I got so much help
from this forum.


I use R on windows as well.  After install R, if the R is not on the
desktop, go to: start - program - R, make the short cut on the desktop.
(If this is not what you are asking, please post the question again.)

Hope this helps.  

My D. Coyne

Hi Mark,

Thank you for the reply.

I meant the command prompts to start an R file.

To be followed on by importint data I can then use to practise the software
with. The installation did put an icon on teh desktop. I am a very skilled
user of computers but command lines for many programs is something that cna
throw me sometimes!

 Hi Rthoughts,
 
 It isn't clear what you mean.  When you install R, the installation
 program usually puts an icon on your desktop that you can click on to run
 the program.  So, if you don't have that, but have installed R, and what
 you mean is, How do I start the R program? or How do I run R? then do
 the following:
 
 Go to the directory where R has been installed.  If necessary, use your
 file manager to find the file named Rgui.exe.  When you have found it,
 execute it to start an R session.  (Rgui.exe usually lives in something
 like: ...\Program Files\R\bin\)
 
 Later you will find out how to set this all up properly.  Usually the
 installation program does a faultless job.

 Mark.

Re: [R] Getting started help

[gatemaze]

Hi, if  I may further add it would be very helpful if you get a book on R
from your library... the introductory chapters should be very much helpful
as all of them start on how to simply start R, load your data files, etc
etc The deepness and power of R is well beyond any other software, but
you do have to use your keyboard more than your mouse :). although there are
some GUI's available... when i started using R I used R-commander and rattle
which helped me get started a bit...

Re: [R] Getting started help

[Mark Difford]

Hi Rthoughts,

Yes, I see now that they truly are (just) Rthoughts;) but take courage, for
we are getting closer (to the start).  You still need to read the basic
documentation, and you will get used to the command line.

What I think you need is a package called Rcmdr.  So, start R using your
desktop icon, click on the Packages menu, then on Install package(s)..., and
then scroll down and choose Rcmdr (you will probably first be asked to
choose a download site). For you the TeachingDemos plugin is a good
additional choice.  Click OK.

Once Rcmdr has been installed, type the following at R's command prompt:

require(Rcmdr)## loads Rcmdr and runs it

You can now switch windows between Rcmdr and R.  Again, at the R prompt type
the following commands:

require(datasets)
?datasets
data(ChickWeight)  ## careful: R is case sensitive!
ls()   ## try ?ls

Now, switch to the Rcmdr window and use the Data set: button to load
ChickWeight into Rcmdr's workspace.  Now mess with it; or load another data
set, more to your taste.  Use Rcmdr's Tools menu to load any plugins you
installed.

ls()
str(ChickWeight)## try ?str
summary(ChickWeight)
?rm
rm(ChickWeight)
ls()

HTH, Mark.
