similar to: Setting hostname in the .Renvironment

Our lab has a lot of different unix boxes, with different hardware, and I'm assuming (perhaps wrongly) that by setting a per-user package installation directory, the packages will only work on one type of hardware. Our systems are all set up to share the same home directory (and, thus, the same .Renviron file) -- so, is there a way to set, in the .Renviron file, per-computer or

Hi, I have Debian Testing running on a Lenovo Thinkpad X1 Carbon (2015, 3rd gen.). I would like to have a package library independent of the installed R version. Under Ubuntu, I used to have the following line in ~/.Renviron: R_LIBS=/usr/local/R/library:/usr/lib/R/site-library This worked fine and /usr/local/R/library showed up in .libPaths(). However, under Debian (with the same ~/.Renviron),

This is probably a very noobish question, but if I want to create a function that allows an undetermined number of, say, numeric vectors to be fed to it, I would use: myfunction = function(...) { # Do something } Right? If so, how do I a) count the number of vectors "fed" to the function, and b) how do I treat those vectors as variables, e.g. for the call:

R-helpers: I'd like to be able to store all the file information from an ftp site (e.g. file and foldernames) through an R command. Any ideas how to do this?

R-helpers: It looks like http://finzi.psych.upenn.edu/search.html has stopped spidering the mailing lists -- this used to be my go-to site for searching for R solutions. Are there any good replacements for this? I want to be able to search both functions and mailing lists at the same time. Cheers! --j -- Jonathan A.

AFAIU, 'R CMD check --as-cran' tries to hide any site and user package libraries by setting R_LIBS_SITE and R_LIBS_USER. However, contrary to R_LIBS_SITE, it fails for R_LIBS_USER and the user's personal library is still available for test scripts. Should I revise my assumptions, or is that intentional? The short version. Shouldn't: $ R_LIBS_USER='' Rscript --vanilla -e

Hi, I am interested in customizing the installation of R. I have gone through the ?R Installation and Administration? manual. But some of the stuff is not clear to me and I would like to get clarifications on the following points (for a Windows installation with R_HOME=C:\\R\\R-2.9.1 ) : 1. I understand that I need to create a file, .Renviron with the following path : R_HOME\\etc\\.Renviron where

I have not intentionally set R_LIBS_USER. I looked for an Renviron.site file but did not see it in R/etc or my home directory. The strange part is that if I print Sud.getenv I see a value for R_LIBS_USER. However, this directory is not showing under libPaths. I though .libPaths should contain R_LIBS_USER. I also noticed that R related variables are not in the system or user variables because I

R-helpers: What would be the absolute fastest way to make a large "empty" file (e.g. filled with all zeroes) on disk, given a byte size and a given number number of empty values. I know I can use writeBin, but the "object" in this case may be far too large to store in main memory. I'm asking because I'm going to use this file in conjunction with mmap to do parallel

Hi Here's a warning for you. If you start R today and it can't find any packages in your home directory that it did find yesterday, don't faint. You'll see something like this: > library(data.table) Error in library(data.table) : there is no package called 'data.table' and your user home folder R packages will no longer appear in path: > .libPaths() [1]

Martin, I am aware of --vanilla; I use it myself for some testing. In this case R_LIBS_USER was set externally (part of my login) and does not involve any of the R scripts. That means it is inherited by any subprocess. For example: tmt1495% R --vanilla --no-environ R version 3.3.1 (2016-06-21) -- "Bug in Your Hair" Copyright (C) 2016 The R Foundation for Statistical Computing

Hi An upgrade to R 3.4.1 on Ubuntu removed the default setting of R_LIBS_USER in /etc/R/Renviron. What's the rationale behind this? Thanks. Best regards Kirill

Dear Johannes, Dear Dirk, Thanks a lot for helping. Here is the missing information. Here is how I installed R. This is basically how Martin Maechler showed me to install R under Ubuntu (in several versions so that they are also recognized by ESS). My goal is to adjust this to make it work for Debian: 1) sudo emacs /etc/apt/sources.list # then add: deb

dear dirk, i am following up on our thread on r-help-mailinglist. you advised me to bring it over here. when installing packages from within R, they usually go to a directory defined in R_LIBS_USER, which i have it set in .Renviron. when installing packages via sudo apt install r-cran-.., they go to /usr/lib/R/site-library. is there a possibility to have packages installed to the R_LIBS-USER

R-helpers: Say I have two lists of arbitrary elements, e.g.: list1=list(c(1:3),"R is fun!",c(3:6)) list2=list(c(10:5),c(5:3),c(13,5),"I am so confused") I would like to produce a single new list that is composed of all combinations of the "top level" of list1 and list2, e.g.: listcombo=list(list(list1[[1]],list2[[1]]),list(list1[[1]],list2[[2]]

R-helpers: I'm trying to install a package from r-forge, and I'm wondering if there is a way to force R to install a package, even if the package "requires" a certain version of R (short of modifying the DESCRIPTION file)?

R-helpers: I'm curious what support R has for parallel writes to a binary file? If I want to use snow to have each node write different "rows" of a flat binary file (possibly out of sequence), are there any tricks/issues I should be aware of? --j -- Jonathan A.

Folks: I'm trying to port some code from python over to R, and I'm running into a wall finding R code that can solve a generalized eigenvalue problem following this function model: http://docs.scipy.org/doc/scipy/reference/generated/scipy.linalg.eig.html Any ideas? I don't want to call python from within R for various reasons, I'd prefer a "native" R solution if one

I want my local libraries to have priority over the system installed ones, which, as far as I can make out from help(".libPaths"), means they have to come first in that list (it doesn't actually_say_ so, but that seems to be the idea). We have R_LIBS_USER which looks made for specifying where I keep my own libraries. Unfortunately it comes last in .libPaths() [which appears to
