[R] cat() to STDERR

[ivo welch]

Dear R wizards---I read Brian Ripley's post from 2004 which said that
it was not possible to print to STDERR.  Alas, I have more modest
needs.  I was wondering if it was possible to just send a string to
STDERR with cat() while in CMD BATCH mode.

Is it not possible to open STDERR in R?  (Or does R use STDERR for
itself and redirect it into the output stream?)

This would be on a standard Unix (gentoo) system and R 2.4.x.
