Sorry for posting a possibly stupid question.
I am using aov() for calculating ANOVA as follows:
summary(aov(depVar~factor1*factor2+Error(subject/(factor1+factor2)),
data=anovaAllData))
and usually all works fine.
How exactly the call has to look if I want to use lm() directly to
obtain the same results.
The problem is that due to several reasons I am missing single data
points such that I end up with an unbalanced design. From earlier
posting I learned that lm() is the way to go in such cases.
However, I do not know how exactly the formula including the error term
has to look like for lm().
Hope that made sense,
Thanks in advance,
Jan
