Is there anyway to have a function prompt the user for a working directory, equivalent to file.choose()? --Paul

If I have a data frame something like: Value=rnorm(30) Group = sample(c('A','B','C'), 30, replace=TRUE) df = data.frame(Value, Group) It seems like it should be simple to create an 'ObsID' column which indicates the observation order of each Value within each of the 3 groups. Somehow, I can't quite see how to do it without manually sub-setting the parent data

This is a bit of a cross-post but I've encountered what appears to be a parsing error with RTools on Windows in a couple of different contexts on Widows when R is installed on a secondary drive to avoid using precious space on my c:/ solid state drive. This type of apparent parsing error has has occurred several times previously when install source code from GitHub, and most recently when

Is it possible to write functions in such a way that, rather than having to write "a=function(a)", one can just write "function(a)" and have the variable passed as the argument be modified? My real interest here is being able to invoke the editor by writing "ed(filename)" rather than filename=edit(filename). Thanks, --Paul

I encountered this issue a couple of months ago and resolved it by installing Rtools in the default directory C:\Rtools, see below for details. I didn't have time to prepare a proper error report and in fact suspected that I may be messing up something. I tracked down the error by installing from the command line, rather than with install.packages(). On Windows I keep multiple versions of

Is there an easy way to make the error bars the same color as the points and lines they are plotted with. My example # fake data x=sample(1:10, 100, replace =T) y = rnorm(100) + runif(100) df=data.frame(x,y) # summarize data m = aggregate(df,list(x),mean) se = aggregate(df,list(x),sd)/sqrt(10) library(Hmisc) plot(x,y) errbar(m$x, m$y, m$y+1.96*se$y,

I got the following: > library(foreign) > swal = read.spss("swallowing.sav", to.data.frame =TRUE) Warning message: In read.spss("swallowing.sav", to.data.frame = TRUE) : swallowing.sav: Unrecognized record type 7, subtype 21 encountered in system file > The bulk of the data seems to read in a usable form, but I'm curious about what might be getting lost

I recently updated all my plugins, and for the fun of it, I added ALL the Rcmdr Plugins to my collection to see what functionality might exist. I started Rcmdr and loaded ALL the available Plugins from to the Rcdmdr Tools menu. To my suprise Rcmdr produced a number of warnings and finally an error. The error suggests that some of the extensions are incompatable with each other because of menu

If I'm not mistaken, "bundle" is really only useful as a concept for distribution and installation. You distribute and install a bundle, but load the individual packages when you want to use them. Once you install the bundle, you won't see the name of the bundle in the list of installed packages, but you see the constituent packages, and those are what you load when you want to

I have been looking at some 'table' examples in Peter Dalgaard's ISwR book, and I am confused by how to get right justification of my table headings when I use the tables() command. Compare the following: # Produces right justfified column names caff.marital=matrix(c(652,1537,598,242,36,46,38,21,218,327,106,67),nrow=3,byrow=T)

Hmmm, you may know winbuilder: It has R not installed oin drive C: and works well. Even with R installed on a network share I can easily install packages. using R-devel binary in, e.g. for 64 bit: in d:/RCompile/recent/R/bin/x64 working directory: d:/library-devel specified library: c:/tmp > install.packages("GO.db", lib="c:/tmp") installing the source package

Dear R-devel mailing list, I am wondering whether the "theta" and "phi" parameters of the "persp" function in the graphics commands are named in error (the names seem to have been swapped). Also, in the documentation to "persp", reference is made to "colatitude" when the effect in the image is actually that of "latitude". Thank you,

I wrote a little routine to convert multiple spss data files (as data frames) to R data files. The code is as follows: # list=dir(pattern=".sav") library(foreign) for (i in 1:length(list)){ # The saved data frame will be dat dat=read.spss(list[i],to.data.frame=TRUE) name=substring(list[i],1,nchar(list[i])-4) rname=paste("../R/",name,".rda",sep="") # This

I have seen several posts (but few answers) in "R-help search" as to whether there are any packages that use R to process digital images. There are several categories related to the general type of problem that are useful to know about: -- Any existing packages for taking a digital image format {any flavor like TIFF, jpg, png, or GIF (or even TWAIN input)} and representing it internally

Example data in a recent post was: LandFill Ruminants United States (USA) 7777.214280 5528.16 France 200.527083 1299.87 Australia 185.878368 2448.17 Russian Federation 1752.833400 2024.29 Argentina 283.987320 2567.02 Brazil 1048.422480 8839.61 Colombia 265.125000 1307.61 Mexico

In following a thread on this mailing list, I encounter an apparent issue with **Edit | Paste commands only** in the Windows R-GUI. Reproducible steps: Go to (using IE?): http://www.r-bloggers.com/select-operations-on-r-data-frames/ Find the section entitled 'Duplicate row names' Copy the following lines from the web page < a = matrix(1:18, nrow=6, ncol=3) < rownames(a) <-

Current behavior is to have to choose a CRAN mirror the first time a package is installed in a session. The closest mirror site is always the same for me, and I wouldn't wish to change it unless it

Hi, maybe (probably ??) it's me, but it took me more than a week to get winbindd working on Redhat 9. It works now after changing a parameter in smb.conf, but I have NO idea why. Maybe some of you already had the same problem. If so, PLEASE clearify ! Thanks... PS as you will see later, getent group also does not work. This is an independent problem I think... can it have something to do

Since upgrading to 2.12.0, I'm having trouble getting the JGR to start under Windows 7, but I'm not quite sure what's happening. When I try to run the JGR.exe stub, the dialog says can't find Java R interface jri.dll. As nearly as I can tell from a Google search this is to be a part of the rJava package which seems to load fine with the library(rJava) command from the Windows R
