repeated measures aov with weights
Dear R-help,
I'm facing a problem with defining a repeated measures anova with

# generate some data
seed=11
rtrep <- data.frame(rt=rnorm(100),ti=rep(1:5,20),subj=gl
(20,5,100),we=runif(100))
# model with within factor for subjects/repeated measurements, no
problem
aov(rt~ti + Error(subj/ti),data=rtrep)
#model with weights and subj as between factor, ie ignoring repeated
measures,
#again, no problem
