Dear lmer list

I have one within-subject factor with 3 levels (A1 A2 A3). By default, I
will get an intercept for the reference group (A3) and two estimates for A1
and A2 compared to A3. How can I get an estimate for the main effect of
factor A as the traditional ANOVA does? Is there any function or option that
allows me to have an overall test?

In addition, if I have two within-subject factors (A1 A2 A3 and B1 B2) and
their interactions, I will get 2 estimates for factor A, 1 estimate for
factor B and 2 estimates for the interaction. A similar question is, how can
I get an estimate for the interaction as the ANOVA does?

Thanks a lot.

Best,
Miao-Hsuan Yen
