Howdy, In the past, I've just run the ANOVA as normal, and then just grabbed the appropriate MS for the estimation of F ratios. Eg, this will get you the MS in your anova object: summary(obj.aov)[[1]][3] or summary(obj.aov)$Mean And if you want a specific MS, summary(obj.aov)[[1]][[1,3]]

Greetings to all, This is my model: aov.fit<-aov(Y~A+B+C+D+E+A:C+A:E) In summary(aov.fit) all F values are comptuted by eg MS(A)/MS(Residuals). This is not correct (or what I want), except for F(B) and F(A:E). I suppose P values are not correct either. Is it possible with aov to define the way
