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:
Who said it would? By the time you set these, tempdir() is already
created.
Set TMPDIR before you start R, e.g. on the RGui command line.
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()

attached base packages:

loaded via a namespace (and not attached):

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
