Hi all, I search the archive for finding a simple solution for using TukeyHSD with a multistratum aov result (a repeated emasure anova). The Question have been asked but I've found no clear answer. res<-aov(y~Fa*Fb+Error(Subject/(Fa*Fb)) ) I think that the problem is that res is an aovlist object instead of the "aov" object required by TukeyHSD. Is there an easy solution to this problem ? Sylvain Cl?ment Sylvain CLEMENT (MCF) JE Neuropsychologie et Cognition Auditive UFR de Psychologie BP 60149, Universit?

It's much easier to handle, and there is excellent documentation including a book by the authors of the package (Pinheiro/Bates). However, a ready made multiple-testing procedure is not available for lme. Package multcomp provides one for lm type models, and Thorsten Hothorn has shown how it could be used with glm (and possibly lme in a similar way). http://finzi.psych.upenn.edu/R/Rhelp02a/archive/21117.html Dieter
