Hi Bernhard,

When you are interested in so many groups and to compare them, why not use a cluster technique or a mixture approach to get some grouping

Onderwerp: [R] Create grouping from TukeyHSD (as a duncan test does)?


Hello everybody

1. If there is/ever will be a function to perform "duncan multiple range test" please inform me at once.

2. Is there a way to create a grouping as duncan does from TukeyHSD output? My experimental design contained 62 genotypes, so the pairwise comparison is not that usefull and clear to look at. How would I do that? Is there an other test that does give grouping as output?

Thnaks for your help.
