[R] Two factor (or more) non-parametric comparison of means

[Marc Schwartz (via MN)]

I suspect that John may be looking for ?friedman.test, which I believe
will allow for a two-way non-parametric test.

kruskal.test() will perform a non-parametric test on two or more samples
(or factor levels) as a generalization of wilcox.test() for one or two
samples (or factor levels).

HTH,
