Hi All, I am learning R and having a little trouble with the usage and proper definitions of data.frames vs. matrix vs vectors. I have read many R tutorials, and looked over ump-teen 'cheat' sheets and have found that no one has articulated a really good definition of the differences between 'data.frames', 'matrix', and 'arrays' and even 'factors'. I

This is the first time that I have tried to update packages with a tinkered around with .Rprofile. I start R with R --vanilla and it does not load my .Rprofile, but when I issue the command update.packages() R downloads the packages as expected, but then seems to load .Rprofile before compiling the packages sources. What am I doing wrong? kindest regards, Stephen Sefick see- Session info

Greetings all, I have been working with RStudio and R only for a little while. I came across a package called 'reshape' that helped me 'rename' columns. Unfortunately, my computer got hosed (too much playing with linux too late at nite) and I had to re-install everything, BUT when I tried to reinstall 'reshape' or 'reshape2' I COULDN't. Is there a way to get

In my shell environment, I have set a path to R_PROFILE_USER. The file, Rprofile.R, is a collection of small hacks. I want to build rstudio-server from source. Best is to $ unset R_PROFILE_USER before. Unfortunately, this has no effect on my system. ----------------------------------------------- poisonivy at poppy ?? ~ % R *** Successfully loaded .Rprofile *** Welcome back poisonivy working

I would appreciate some advice on what the preferred contents of RProfile.site vs. .Rprofile should be. A .First() function can reside in either one, but is it preferred to place it in .Rprofile? I currently use .First() in .Rprofile files placed in separate directories used for different RStudio projects. Thank you [[alternative HTML version deleted]]

Greetings all, I would like to append a 4 digit number suffix to the names of my files for later use. What I am using now only produces 1 or 2 or 3 or 4 digits. ############ for (i in 1:1000) { temp <- (kegg [i,]) temp <- merge (temp, subrichcdt, by="gene") file.name <- paste ("kegg.subrichcdt.", i, ".txt", sep="")

Dear guRus, I'm maintaining central R installation (Linux) for our institute. The startup screen of R traditionally echoes some messages (starting with "R version ...Copyright (C).. The R Foundation for Statistical Computing...") and I'd like to display for example right after these messages some other messages about our specific setup, how to contact me etc ... What

Hi, I am not not sure whether this topic belongs to this mail list, but I feel the subscribers here should be the right audience. I noticed that the memory limit reported under Windows is 16 GB. I am wondering how to increase it. I didn't found anything in Rprofile.site nor .Rprofile. Is this limit hard coded at compilation? Best, Samuel [[alternative HTML version deleted]]

As Jeff says, it might be that you have a ~/.Rprofile file with instructions to load packages when R starts. It could also be that you have a .RData file, which is saved if you answer yes to: > Save workspace image? [y/n/c]: y when you quit R. If this file exists, then R loads it and all the objects you had when you saved it. If there are objects associated with packages, then that will

Greetings all, I am calculating two t-test values for each of many files then save it to file calculate another set and append, repeat. But I can't figure out how to write it to file and then append subsequent t-tests. (maybe too tired ;} ) I have tried to use "dump" and "file.append" to no avial. ttest_results = tempfile() two_sample_ttest <- t.test (tempA, tempB,

Can you be more specific about what conditions cause R to automatically load a package when a .RData file is loaded? My experience has actually been the opposite.

Might seem drastic to some, but I don't feel much pain because I almost always edit my code in a file rather than on the fly at the console, and re-run it frequently from a fresh R process to check my progress.

Greetings all, I am getting this error that is driving me nuts... (not a long trip, haha) I have a set of files and in these files I want to calculate ttests on rows 'compareA' and 'compareB' (these will change over time there I want a variable here). Also these files are in many different directories so I want a way filter out the junk... Anyway I don't believe that this is

I am new to R and have recently tried Tinn-R with very mixed and unexpected results. Can you point me to a Tinn-R tutorial on the web or a decent reference book? Thank you for your help; Charles McClure cmcclure at atrcorp.com cfmcclure at verizon.net

The x11() window can be a nuisance to have popping up at startup (esp. on small screens) when you're not working with graphics. However, currently you can't get rid of it without modifying the systemwide Rprofile. Current logic is: Run $RHOME/library/Rprofile if ./.Rprofile exists run it else if $HOME/.Rprofile exists run that endif I think it should be Run $RHOME/library/Rsetup if
