[R] How to do multiple comparisons with multiple error strata

  the title says it all. I have an ANOVA model with
"Error" term and the functions TukeyHSD or those
from the "multcomp" package seem not to work with
such a model. Assuming that the object returned from
aov() function with multiple strata is a list of aov objects,
I tried something like TukeyHSD(aov.1$Within), but this
does not work either.
 Does somebody have a solution? I think I can calculate
confidence interval for individual coefficients, extending
interval ranges based on Bonferroni correction, but this
seems to be too crude solution...

Thank you,        Petr Smilauer
