m0<-lm(rich ~ gap*stage,data=richness) cc<-contrast(m0, a = list(stage="A",gap="0"), b = list(stage="A",gap="1")) m2<-lmer(rich~gap*stage+(1|site),family=poisson,data=richness) # plug in matrix from contrast(m0) summary(glht(m2, linfct = cc$X)) ok, this works fine - for each stage seperatly.. but what if i needed all 4 gap effects within each of the stages? i think that then it may be needed to test "gap" within each stage simultanously so that the p-values will be adjusted accordingly, isn't it? is this possible? - if so, how would this be done? anyone who can help with this.. best, kay ----- ------------------------ Kay Cichini Postgraduate student Institute of Botany Univ. of Innsbruck ------------------------ -- View this message in context: http://r.789695.n4.nabble.com/contrasts-for-lmer-model-tp2222682p2222743.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
