Subject: Planned contrast on repeated measures
I have an anova model that looks like this:
aov(log(Y)~X+Error(Participant/X))
Is there a way to do a planned contrast on a repeated measures
model... something with an error term? I get an error when I do this:
contrasts(X)=cbind(-3,-1,1,3)
summary.lm(aov(log(Y)~X+Error(Participant/X)))
Any help would be appreciated!
