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] "C:\\Users\\skoiejo\\AppData\\Local\\Temp"
> Sys.setenv(TMP = "e:\\Temp\\Rtmp")
> Sys.getenv("TMP")
[1] "e:\\Temp\\Rtmp"
> tempfile()
[1] "C:\\Users\\skoiejo\\AppData\\Local\\Temp\\Rtmp2tvQ7U\\file499a5987"
# I have also tried to change "TMPDIR", "TEMP" and "R_USER", all with
the same result.
# The directory is writable:
> write("some text", file = paste(Sys.getenv("TMP"),"test.txt",sep = ""))
> list.files(Sys.getenv("TMP"))
[1] "test.txt"
I have probably misunderstood something, but what? Session info below.
> sessionInfo()
R version 2.14.0 (2011-10-31)
Platform: x86_64-pc-mingw32/x64 (64-bit)

States.1252 LC_MONETARY=English_United States.1252

States.1252
attached base packages:
[1] stats graphics grDevices utils datasets methods base
loaded via a namespace (and not attached):
[1] tools_2.14.0
I know this is not the last version, but I do not have administrator
rights myself on the computer and did not see any relevant references to
tempfile() in the news for newer versions.
Thanks,
Jon
