similar to: setting environmental variable inside R function to call C function

Right. glibc's amusing stance is that you setenv/putenv are not thread safe, but getenv is. I assume Ruby exposes setenv and therefore simply not calling setenv isn't an option. Would it solve your problems if all getenv() calls happened at cl::ParseCommandLineOptions() time? On Thu, May 23, 2013 at 9:49 AM, Dirkjan Bussink <d.bussink at gmail.com>wrote: > Hello, > >

Hi, I see some weird behavior when loading a specific dataframe after changing the value of an enviroment variable using Sys.putenv(). Alas, I can't reproduce it from an arbitrary dataframe.

I use a Mac (10.4.11 Mac Os X). In my .tcshrc I define an environmental variable MY. Is it possible to find out its value from inside R? When one loads R for Mac OS X Cocoa GUI written by: Simon Urbanek Stefano M. Iacus are files like .tcshrc read by R? Can I make the value of this environmental variable available to R? Sys.getenv() produces a lot of output, with the values of many

Dear list, this is not directly an R question, but it is somewhat related to R aspects, so I hope it's okay to post it here: I'd like to update my windows PATH based on a script routine in order to make sure that crucial components are contained. Much like what happens at the installation of Rtools (if desired). Now, can you do that from within R or do I need some sort of windows

Hi, I recently had some difficulty getting an embedded R session running on Windows, due to the way that R Sys.getenv works, which I would consider a bug. Even if you do not agree, then you may still want to document it for future users who might be bitten. As outlined in R-exts (?8.2.2): http://cran.r-project.org/doc/manuals/r-release/R-exts.html#Calling-R_002edll-directly R_HOME/bin needs to

Environment variables set with Sys.putenv() "disappear" spontaneously (and somewhat randomly) when I load large datasets. This was reported in R-help by Dave Kane on June 4, 2001; I have not seen any further discussion. I'm not sure if I can report it as a "bug", since it is not entirely reproducible. Could someone try this and see if you have trouble too? The following

(As a non-root/non-admin), I've just tried to figure out how to prevent a default $R_HOME/site-library/ to be added to the library path. The solution I found was to environment variable R_LIBS_SITE to ":" (preferably in ~/.Renviron). Note that setting R_LIBS_SITE to en empty string will cause it to fall back to using $R_HOME/site-library/. This "hack" is based on the

Hello, In Rubinius we're seeing an occasional crash inside LLVM that always happens inside getenv(), which is used for example when creating a MCContext (inside lib/MC/MCContext.cpp, it checks getenv("AS_SECURE_LOG_FILE")). The problem is that getenv() and friends aren't thread safe and Rubinius provides a multithreaded system. We can relatively easily get locking setup around

It is the shell that does the ~ and $ expansions, and Sys.setenv() doesn't go via the shell, so you cannot expect it to understand the shell metacharacters. Instead, you need to do the corresponding computations in R, e.g. > paste(path.expand("~/mypath"), Sys.getenv("PATH"), sep=":") [1]

?tempdir says By default, ?tmpdir? will be the directory given by ?tempdir()?. This will be a subdirectory of the temporary directory found by the following rule. The environment variables ?TMPDIR?, ?TMP? and ?TEMP? are checked in turn and the first found which points to a writable directory is used: if none succeeds ?/tmp? is used. Unfortunately, it doesn't seem to

This also defines SOEXT as the extension of shared objects (ie. "so" or "dll"), and uses it everywhere. I assumed this must already be defined by either autoconf or mingw (like OBJEXT) but I cannot find anything except in glib (G_MODULE_SUFFIX).

Hi all, I would like to know if there is any way to evaluate the values in `Sys.setenv` before setting the environment variables. For example, if we want to add a path to the environment variable `PATH`, we can do this in a terminal ``` > export PATH=~/mypath:$PATH > echo $PATH /Users/jeff/mypath:... ``` However, this style of assignment is not allowed in `Sys.setenv`, it treats its

I decided my earlier email on this topic was rather long and wordy; here's a condensed version. I am sitting at a Solaris computer in the US/Pacific timezone. I have a file of data having times that includes the following three values 2002-4-7 1:30:00 GMT 2002-4-7 2:30:00 GMT 2002-4-7 3:30:00 GMT I have not been able to find a way to correctly convert these to either of the POSIX

Hi, One of the functions I use needs to write to a temporary file, in the directory given by tempdir(). I want to change this from the standard one, as the file is too large for the drive. However, tempfile() doesnt seem to respect the environment variables when I change them with Sys.setenv(). In a fresh R-session: > Sys.getenv("TMP") [1]

Hi Everybody, I been looking through google for better part of the day but I haven''t been able to find an answer to my problem. I need an environmental variable to be present in puppet, so that yum works correctly. However after reboot puppet doesn''t read /etc/profile and starts without this profile. If I go into server and do services puppet restart than everything works fine,

I am running R-1.3.0 on Solaris 8: Under Solaris I do setenv dendro_us hoffmann echo $dendro_us gives back: hoffmann which is correct. When in R I do: Sys.getenv("dendro_us") I get dendro_us "" which is NOT correct: Inverse effect (taken from help of Sys.getenv) Under R: print(Sys.putenv("R_TEST"="testit", ABC=123)) [1] TRUE TRUE

Using "Sys.getenv()", I got a list of 380 environment variables... Now I open a new R session, how do I set those environment variables in my new R session using "Sys.setenv()"? There is no batch function for "Sys.setenv()"? Is there an import/export environment variables function? Basically I want to export all the environment variables from one R session and
