[R] Post-hoc and planned comparisons for repeated measures

[Krehbiel, Dwight]

Dear colleagues,

Can anyone give some clues about how best to conduct post-hoc comparisons or planned comparisons for repeated-measures data in R? The UCLA web site gives wonderful examples for doing repeated-measures analyses of variance, but pairwise or other comparisons are still escaping me. Any clues would be much appreciated.
