aov define F values computation

Question

Greetings to all

This is my model: aov.fit<-aov(Y~A+B+C+D+E+A:C+A:E, data=dat)

In summary(aov.fit) all F values are computed 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.

Can I specify how the F computations will be done? I 'd like them to be like this: F(A)=MS(A)/MS(E), F(C)=MS(C)/MS(E), F(D)=MS(D)/MS(E), F(E)=MS(E)/MS(A:E), F(A:C)=MS(A:C)/MS(A:E)

thanks
