Thank you, Peter,
but note that this is clearly too late for 2.3.0 :
If you look at the release schedule at
http://developer.R-project.org/
you see that April 10 was "Feature Freeze".
If it looks good -- and it does after a quick glimpse --
it should be possible to be integrated for 2.3.1 though -- but
that is not at all scheduled yet.
With regards,
Martin
