[R] Error for TukeyHSD ?

[Silvia Lipski]

Hi,

one question about TukeyHSD in R:

it seems to work only for models without Error terms but not when an  
Error is specified:

Examples:

aov1<-aov(MMN_ind~(GenCond*Lang)+Error(VP),data=cutie_all)
TukeyHSD(aov1,"Lang",ordered=TRUE,conf.level = 0.95)
--> the German error  message tells me its not a method that can be  
used with TukeyHSD:
Fehler in TukeyHSD(aov1, ordered = TRUE, conf.level = 0.95) :
         keine anwendbare Methode für "TukeyHSD"

A model like this is no problem:
aov1<-aov(MMN_ind~(GenCond*Lang,data=cutie_all)

I am very grateful for any help!
Silvia
