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

Hi Dwight, The answer likely depends on how you are fitting the model. Have a look at the multcomp package and its vignettes to see if it can handle the model class you are interested in. hth, Kingsford Jones On Sun, Mar 29, 2009 at 11:11 AM, Krehbiel, Dwight <KREHBIEL at bethelks.edu> wrote:> Dear colleagues, > > Can anyone give some clues about how best to conduct post-hoc comparisons or planned comparisons for repeated-measures data in R?
