I'm not doing this on purpose, but I seem to be out of town only when the KC R group has meetings <g>. I'll be gone again in August, but I'll try to be in town for the next one.
The following is more of a statistics topic than just R, but I recently found this an interesting article to estimate p-values -- perhaps this would be fun to discuss as a side topic some month:

That sounds good to me... Earl, we'll catch you in October, hopefully!
