It's awesome to see so many local R user groups kicking off in 2011! Yet another is the Austin R User Group in Austin, Texas. They've already held their first informal get-together, and the first formal meeting on February 23 will be devoted to data management techniques in R. Props to Sandy Donlon for organizing the group!
And I'm so pleased to report that a local R user group has started in my old hometown of Adelaide, South Australia. Organized by Jonathan Tuke at the University of Adelaide (my alma mater), the Adelaide R-users Group has already had several successful meetups and their next meeting is on February 28. Australia now has an R user group in every major city except Perth, which I'd venture makes it the country with the most R groups on a per-capita basis. (And yet, ironically, still no groups in New Zealand — c'mon Kiwis!)
