Re: [R] Letter-based representation of pairwise comparisons

Ok, thanks for all your responses, i was thinking, after reading the firsts messages that use only the $p.value was good. By using a symetric matrix results are ok. It's also good with a pvalue vector (just like exemples in the help ...). many thanks for your help -- View this message in c

Re: [R] Letter-based representation of pairwise comparisons

hello, i try to use the multcomp letters, but i have problems with my results : here is my pvalue matrix (from a pairwise.t.test) : pair=pairwise.t.test(...) pair$p.value 0 BBxS B0.01727- - BxS 0.000130.00226 - S0.87
