I wrote the message below, but it's just plain wrong.
The CMD.EXE shell in Win XP (and 2K?) allows redirection of stderr in
the usual Unix style:
Rterm --no-save --no-restore < "Rscriptfile" > "Rstdoutfile"
You can also use "2>&1" to redirect stderr into the stdout stream, so
both go to Rstdoutfile.
