newbie question on contrasts and aov
...f
contrasts(Spk.selected.df$spk) <- contr.sdif(4)
aov(erp ~ spk + Error(sub), data=Spk.selected.df) -> Spk.aov
summary(Spk.aov,data=Spk.selected.df,split=list(spk=list(p=1,q=2,r=3)))
this is the the beginning of the dataframe, which I use:
sub spk erp
1 10oddball spk1 2.587
2 11oddball spk1 -0.335
