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)
Error: Tpt
Df Sum Sq Mean Sq F value Pr(>F)
Residuals 1 87.999 87.999
Error: Tpt:Tek

Tek 3 1154.81 384.94 42.823 0.005812 **
