yes, thank you, Gabor .....
and we (the R developers) have accepted and incorporated
quite a few constructive proposals for improvement.

You can also decide to leave this mailing list and get the money
back you paid for that service. Unfortunately, we can't get the
time and energy back we've lost when dealing with such postings...
