exact wilcox test and Bonferroni correction
?p.adjust Apply that to a vector containing all p values you get from wilcox.exact. Alternatively, multiply each p value by the number of comparisons you perform, see any textbook for that. You might want to consider a less conservative correction, though. HTH, Michael

I found the function pairwise.wilcox.test. However, my data have ties. I know that when there are ties is better to perform Mann Whitney test using the function wilcox.exact. How can include in that the Bonferroni correction? thank you for your help! netrunner -- View this message in context: http://n4.nabble.com/exact-wilcox-test-and-Bonferroni-correcti
