[R] define F-ratio computations with aov

2010-03-17 Thread Galanidis Alexandros
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

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,
