[R] R: RE: Bonferroni post hoc test in R for repeated measure ANOVA with mixed within and between subjects design

[angelo.arcadi at virgilio.it]

Dear Michael,
thank you for your answer, however, I am not asking for the tukey
with the bonferroni adjustment, but doing the post hoc with the bonferroni method.
Apparently this is done easily in SPSS, I am wondering whether it is possible with R.

Can anyone help me?

Thanks in advance


Angelo

Untested, but if anything, your best bet is likely something like 

summary(glht(lme_H2H, linfct=mcp(Emotion = "Tukey")), test=adjusted("bonferroni"))

should work (despite the question why you'd want to use Bonferroni rather than Tukey
For a reference, see the book on the topic by the package authors. Might be in the paper, too, which is given by

citation("multcomp")

HTH, Michael
