Hi R users,
I google the website and I found that there are three ways to perform
repeated measure ANOVA: aov, lme and lmer.
http://www.mail-archive.com/[EMAIL PROTECTED]/msg58502.html
But the questions are which one is good to use and how to do post-hoc test?
I use the example that is provided in the above link and I try
tt<-aov(p.pa~group*time+Error(subject/time),data=P.PA)
TukeyHSD(tt)
Error in UseMethod("TukeyHSD") : no applicable method for "TukeyHSD"
Any suggestions?
Appreciate in advance~
Chunhao
