if I do:
yyy=aov(Y~A*B*C);
it seems that the three way ANOVA is based on all fixed-effects.
There is no way to signal to "aov" the A and B are random effects and
C is fixed effect; or A is random and B and C are fixed?
Just put the appropriate Error() term in the model formula.
Moreover, I guess I will need the Expected Mean Squares in order to do
the F-test, where can I obtain these Expected Mean Squares in R?
And is there a command that directly give me the F-tests?
You usually get an stratified analysis, where this isn't necessary.
Notice though that nothing works properly with aov unless the error
factor(s) are completely balanced.
Any good tutorial for mixed linear models in R(e.g. the three-way
ANOVA with two random factors as mentioned above, etc. )
Hmm, there's a bit of a gap there, I suspect. At least the two-way
layout is covered in Baron&Li's tutorial. There also appears to be some
coverage in Venables&Ripley (MASS), but I don't have a copy to hand.
