Thanks, this comes close to what I need, but the problem is that I have
repeated measures in each comparison and SimComp does not seem to handle
this. In my experiments, each subject received both placebo and the drug in
a randomized order. So, I want to do multiple paired t-test corrected for

Hi Erich,
Look at the SimComp package, which handles multiple endpoints, i.e. columns
of response variables. Ratio-comparisons are also handled. Good ready-made
range of comparisons; you can also set up your own.
Regards, Mark.

Well, the measuring time points are 70 170, 300 and 1440 minutes after drug
intake. Since the influence of time is cerainly not linear, I think it's

Thanks, but as far as I know the multcomp package and the tukeyHSD function
can only handle one dependent variable, whereas I have 60 dependent
variables.
