Hi, This post could well be slightly off-topic, and addressed to the maintainer of the package, but I's like to hear from others too. I using the package multcomp (fresh version) with R-1.6.2. I have contrasts matrices of size 42x43 and it takes a fair amount of time to perform a single call to 'simtest' on my data. Anyone with similar problems (I should snoop in the code, but sort of short of time at the moment) ? Thanks, L.
