Yes, TMPDIR needs to be set *prior* to launching R in order for R to
acknowledge it. Although most environment variables can be set in
platform-independent Renviron files which are processed early during
the R startup, TMPDIR is one of the exception - it is simply too late
to set it there because R =needs it very very early on. So, it needs
to be set as in Bill's example above, or similarly:
