Dear list,

I would like to obtain adjusted Sums of Squares, e.g. like those
produced by Anova (car package) (vs. anova, which produces sequential
SS).

I found out that both gls (nlme) and pgls (caper) produce only
sequential SS for their F-tests and Anova doesn't work on objects
produced by gls or pgls.

I know that I can use t-tests of individual predictors, but for
factors with more than 2 levels, this produces tests of individual
levels, not of the factor itself.

Any help much appreciated.
Best regards,
Vladimir
