Your question has been posed on many previous occasions.
The (short) answer has always been the same: have a look at the Anova function in the car package but before doing that, get a copy of John Fox's "Applied Regression Analysis and Generalized Linear Models" book.

Subject: [R] Anova unbalanced
I have got a data set with about 400 companies. Each company has a
score for its enviroment comportment between 0 and 100. These companies
belong to about 15 different countries. I have e.g. 70 companies from
UK and 5 from Luxembourg,- so the data set is pretty unbalanced and I
want to do an ANOVA. Somthing like aov(enviromentscore~country). But the
aov function is just for a balanced design.
So I wonder if I can use fit=lm(enviromentscore~country), anova (fit)
instead? Would this be okay or can it also only be used with balanced
Thanking you in anticipation, best regards
