[Rd] rcmd and directories (cwd; tmpdir) (PR#3429)

[roy_kuraisa at merck.com]

Hi,
rcmd requires a temporary directory identified by the value of the
environment variable "TMPDIR".  Unfortunately, if the directory name has a
space in it, rcmd errors out.  For example, the standard temporary file
"TMP" for xp is like:
 
c:\documents and settings\r_user\local settings\temp
 
If TMPDIR is defined via the Windows/XP "standard" way, i.e.,
set tmpdir=%USERPROFILE%\Temp
 
then rcmd errors out.  Of course if you set TMPDIR to a file without spaces,
all works well unless you cwd has spaces in it and then rcmd will error out
with a message like:
"Cannot cd to c:/Documents "
 
Since there are work arounds (albeit a bit of an inconvenience), I wouldn't
rate this very critical (but some documentation would be nice (at least I
didn't find it in readme.packages; windows faq; reference manual; etc.).
And, btw, for Windows/XP/2000 the default tmp directory is not c:/TEMP --
they changed it to be a function of the user profile (like noted above).

cheers, roy
