Hi, thanks for your answer. Unfortunately I cannot reproduce your results. In my example the results still differ when I use your approach: x - c(10,11,15,8,16,12,20) y - c(10,14,18,25,28,30,35) f - as.factor(c(rep(a,7), rep(b,7))) d - c(x,y) kruskal.test(x,y) Kruskal-Wallis rank

Hello, I think I am right in saying that a 2 sample wilcox.test is equal to a 2 sample kruskal.test and a 2 sample t.test is equal to a 2 sample anova. This is also stated in the ?kruskal.test man page: The Wilcoxon rank sum test (wilcox.test) as the special case for two samples; lm together
