Hi Lorenz,
I really appreciate your comments.

Yes that is exactly I wanted to model.

I'm trying to run a 3-way within-subject anova in lme with 3 fixed
factors (Trust, Sex, and Freq), but get stuck with handling the
random effects. As I want to include all the possible random effects
in the model, it would be something more or less equivalent to using aov

It is not quite clear what you are after, but the 'if' s
Dear Thilo
Thanks for your suggestion. I guess the model you are fitting here has
only a single random effect term, namely subject. If the effect of A
depends on S, one needs to include an additional random effects term
for the S:A interaction.
With lme I can get output for the effect of A which
Dear Kim,
as far as I understandyour problem correct the specification of the model in
lme is:
lme( fixed=y ~ A*B, random=~1|S)

Dear R-users
I'm considering a repeated measures experiment where two
within-subject factors A (2 levels) and B (3 levels) have been
measured for each of 14 subjects, S. I wish to test the effect of
factor A. I know that a variance component model with random effects
S, S:A, S:B and S:A:B can be f
