Re: [R] Error for TukeyHSD ?

[Richard M. Heiberger]

TukeyHSD, and glht in the multcomp package, are designed for
aov objects.  They do not have methods for aovlist objects.

The workaround is to download and install the HH package and look at the
maiz example.

library(HH)
?MMC

In that example I show how to get the same sequential sum of squares
without the Error() term as you would get with the Error term.

[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
