Re: [R] how to do multiple comparisons in R?
Have you received a reply yet? I haven't seen one. There are functions TukeyHSD and p.adjust in the stats package, plus multcomp and multtest packages. If this is not an adequate answer, please submit another question (preferably after reading the posting guide! http://www.R-project.org/posting-guide.html). spencer graves Hongyu Sun wrote: Hi, Sorry I have to bother a question.

Certainly yes and more.

Re: [R] how to do multiple comparisons in R?
R has various methods for multiple comparison procedures. See package multcomp, or ?TukeyHSD or ?pairwise.t.test for example. An RSiteSearch(multiple comparison) returned 187 results. A priori contrasts can be constructed using the make.contrasts function in the gmodels package, for example. We try not to do anything like in SAS. Simon.
