similar to: Problems with environmental variables set with Sys.putenv

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

Environment variables set with Sys.putenv() disappear (i.e. become "") after a while, especially after heavy-duty I/O. Example: R> x <- matrix(1., 3000, 3000) R> save(x, file="myx.RData") R> Sys.putenv(HOME="/tmp") R> while (Sys.getenv("HOME") != "") {cat("ok\n"); load("myx.RData")} The loop prints

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

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

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

The inconsistency is that you use $<- to set the column, then [[<- to change it. Had you tried to set the column by x[[1]] <- as.character(x[[1]]) you would have seen the problem immediately (it does not work as you would have intended). If you want to be sure to turn off conversion to factor, you need to set the column to class "AsIs". My belief is that will behave

Can we get this as a replacement to the current putenv()? It's out of the OpenBSD source tree and is a complete replacement instead of a wrapper around setenv(). Thanks. -------------- next part -------------- #ifndef HAVE_SETENV /* ** Borrowed from OpenBSD 2.6. Some platforms don't even support putenv() ** So therefor we need a real setenv(). */ int setenv(name, value,

Hi Sorry, my first post was in German. I tried to get Rcmdr running under MacOS X 10.4.5. While RGui pretends that tcltk is running, starting Rcmdr freezes R completely. Instead, JGR which gave me the following results: > library(tcltk) Loading Tcl/Tk interface ... Error in fun(...) : no display name and no $DISPLAY environment variable Error: .onLoad failed in 'loadNamespace' for

Full_Name: Kevin Wright Version: 1.5.1 OS: Windows 95 Submission from: (NULL) (170.54.59.160) In the R windows FAQ, item 3.6 (Package TclTk does not work) currently has this line: Sys.putenv("TCL_LIBRARY"="c:/Program Files/Tcl/lib/tcl8.3") I find that if I execute the following two lines after starting R, I can then do library(tcltk) and demo(tkdensity) as usual. I do

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 there, I am trying to distinguish between getOption() and Sys.getenv(). My understanding is that these are both used to set values for variables. getOption is set something like this: option("var" = "A"). This can be placed in an .Rprofile or at the top of script. They are called like this getOption("var"). Environmental variables are set in the .Renviron file

wrapper <- function(){ Sys.setenv(TMP="A") print(Sys.getenv("TMP")) .C("c_fun") } As the example above, I hope to set an env var $TMP inside the R function "wrapper", which affects the functionality of the C function call "c_fun". Also the print line shows that $TMP is set to be "A", but the function call of "c_fun"

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,

Hi, I was trying to update packages with my R 1.6 under RedHat 8.0 system. When entering this command, > update.packages() It simply says, trying URL `http://cran.r-project.org/src/contrib/PACKAGES' But nothing happens. Is this a problem with my proxy setting since I am working behind a firewall? It seems so: > Sys.getenv("http_proxy") http_proxy

I am trying to get the Rmetrics.org component package fBasics by Diethelm Wuertz into a Debian package. Thanks to a lot of work by Diethelm, it is _almost_ there. It fails 'R CMD check' for me if I do not have the TZ environment variable set [1], yet works fine as long as I set TZ. I figured I could patch this in R/zzz.R and do ## set a timezone if none found in environment

Hi folks, I'm having a spot of bother with tempdir(). If I set the environment variable TMPDIR in my shell prior to invoking R it works as expected: > Sys.getenv("TMPDIR") TMPDIR "/eurotempest/tmp/R" > tempdir() [1] "/eurotempest/tmp/R/Rtmp0xY4XD" However if I don't set it prior to entry, but attempt to set it from within

I was trying to install R on a unix server. Because of a firewall i can't install biocLite for working with Bioconductor. With windows it wasn't a problem. I used the option '--internet2' to bypass the firewall. I don't have any idea, how to do it with unix. I tried to set my proxy >Sys.putenv("http_proxy"="http...:8080")
