R help - Jun 2004 - nonparametric two-way structure all-pairwise comparisons

Hello,

I am conducting a two-way analysis of variance. The ANOVA assumption
are not met, hence I need to use non-parametrical methods. In particular
I am interested in all-pairwise comparisons between the levels of one of
the two factors.

If I transform the data in ranks, can I reuse the TukeyHSD method to
produce confidence intervals? If this is not correct, is there any
method implemented in R to produce confidence intervals in the
non-parametrical context?


Thank you for the help!


Marco
