Subject: [R] kruskal.test followed by kruskalmc

Hi all,

After running kruskal.test I have got results (p<0,005) pointing to reject the hypothesis that the samples were draw from the same population.
Howerver when I run the kruskalmc there are no significant differences in any of the multiple comparisons. Is that possible? Some clarification?

Thanks, Humber
