It is too late to set TMPDIR in .Renviron. It is one of the
environment variables that has to be set prior to launching R. From
help("tempfile", package = "base"):
The environment variables TMPDIR, TMP and TEMP are checked in turn and
the first found which points to a writable directory is used: if none
succeeds ‘/tmp’ is used. The path should not contain spaces. **Note
that setting any of these environment variables in the R session has
no effect on tempdir(): the per-session temporary directory is created
before the interpreter is started.**
