Dear R-listers,

I am trying to compute simultaneous confidence intervals with simint from the package multcomp. 230 measures (abundance) have been taken in 23 sites (factor) of a data.frame (donnees: a file can be sent on request, saved with save(donnees,file="donnees")). I would like to get all pairwise comparisons with :

mc<- simint(ren~ID,type="Tukey",data=donnees)

I cannot get a result in a reasonable time (after 2 hours the computer was still working and I interrupted the process).

Can anybody tell me if there is some capacity limitation for simint (as well as for simtest)? Multicomp of Splus handles the problem adequately in a short time, but Splus is practically not accessible for student training...

Kind regards,

Patrick Giraudoux
