The useR! 2010 R users conference just finished up this afternoon with a thought-provoking, controversial, and sometimes hilarious talk by Richard Stallman of GNU fame. It started on Tuesday with great tutorials (I took ones on MICE for multiple imputation and Frank Harrell’s excellent regression modeling). In between these bookends was a wonderful conference where I got the chance to put faces to names (from their online presence), make many new friends, hopefully no enemies, and learn quite a bit.
