Katja,
this can be done by adding an Error() term. Section 6.10

Hello,
is there a function for repeated measures anova? Have searched for some

I don't think anyone pointed you towards the anova.mlm features; you
might find them quite close to what SPSS does. For now, the easiest

Or use gl which directly forms a factor:
group <- gl(2, 5, 30)
time <- gl(3, 10)
subject <- gl(10, 1, 30)

You need, first to factor() your factors in the data frame P.PA,
and then denote the error-terms in aov correctly, as follows:

Christian,
One thing that may help with the data you provide is to make sure that
group, time, and subject are indeed factors.
group <- factor(group)
time <- factor(time)
subject <- factor(subject)

Dear friends
I am not sure that I am conducting this analysis correctly. I would really appreciate
if someone can verify what I've done.
I conducted repeated measures ANOVA for some bugs data. These bugs were measured
repeatedly over 32 weeks at the same trapping plots. I want to test a fu

Hello,
what is the best way to do an ANOVA on two-factor experiments with
repeated measures on one of the factors (e.g. time) in R, (with
Greenhouse-Geisser Epsilon or Huynh-Feldt Epsilon calculation, if
possible (as described in Ott and Longnecker, 2001. Statistical Methods

Dear Jessie,
Why don't you try to use already written functions? Probably lme (in package
nlme) would be what you need. lme comes with documentation, and there is a
whole book devoted to it.
