[R] exact wilcox test and Bonferroni correction

[Meyners, Michael, LAUSANNE, AppliedMathematics]

?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.
