Re: [R] problems with glht for ancova

I answer myself, perhaps it can be useful to anyone. The problem is that I tried to run a psot hoc test before i get the minimal model by deleting the interaction, if I do it: > ancova2<-aov(log(peso)~edadysexo+log(lcc)) > anova(ancova,ancova2) Res.DfRSS Df Sum of Sq F Pr(>F) 150

[R] problems with glht for ancova

I've run an ancova, edadysexo is a factor with 3 levels,and log(lcc) is the covariate (continous variable) I get this results > ancova<-aov(log(peso)~edadysexo*log(lcc)) > summary(ancova) Df Sum Sq Mean Sq F value Pr(>F) edadysexo2 31.859 15.9294 803.9843 <2e-
