I write about R every weekday at the Revolutions blog:
and every month I post a summary of articles from the previous month
of particular interest to readers of r-help.

By the way, you might have noticed that we've changed our name to
Revolution Analytics from Revolution Computing. You can read about the
motivation for the change, and our plans for new products around R, by
downloading the document at:

learn more about Revolution and our products I'll be giving a public
webinar on May 20, details here: http://bit.ly/cQgXxn
