John Fox pointed me in the right direction when I asked this question

before.

Use Anova(lm, type = "III") in the "car" package.

With best wishes and kind regards I am

Subject: [R] Type III Sum of Squares

Hi,

When doing a two-ways anova in R and comparing my same results with an SPSS

output, I noticed that R calculated type I Sum of Squares. Is it possible to

use Type III Sum of Squares?

Thanks,
