[R] Add column to the output of summary(glht).

[PIKAL Petr]

Hi

you can check structure of any object by str so

str(fit0)

should give you an insight how fit0 is structured and

str(SumTukey)

gives you structure of SumTukey object (which is probably list). You can manipulate with the output as you wish according to the rules of R.

Cheers
Petr
