There's yet another local R user group launching this week, this time in Kassell, in central Germany. Their first meeting is on June 24. If my rusty German is holding up, looks like there will be some good discussion on editors and GUIs, how to find packages and functions, and R community resources.
There's been lots of activity in new R user groups lately, which is a great sign. There are now 40 active groups listed in the Local R User Group Directory, with more than come: looks like there may be new groups starting up in Austria and Tokyo soon, too.
