Dear All,

How can I run a multi comparison analysis for a split plot experiment, given that there is a significant diffenece between treatment levels. For example (based on the output below), how can I run multi comparison test for "Tek":

#########################
> tinggi.aov=aov(P18bST~Btg.f*Tek+Error(Tpt/Tek),data=tinggi)
> summary(tinggi.aov)
