[R] how to do multiple comparisons in R?

[Simon Blomberg]

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.
