Thank you, I think multcomp is very near to what I was looking for.
However, I am still looking for a mean to obtain least-squares
(adjusted) means and std. errors of these means, and performing
comparisons among these means, as the LSMEANS do in SAS. I have read
other messages and have looked at car, effects and Design manuals, but I
am not sure if this is what I am looking for. Any clue?
