Hi, I've got a problem building a contrast matrix for the Dunnet contrast in package multcopm. The following works fine: > summary(simtest(adiff ~ trial)) Simultaneous tests: Dunnett contrasts Data: adiff by trial Contrast matrix: trial1 trial2 trial3 trial4 trial5 trial2-trial1 -1 1 0 0 0 trial3-trial1 -1...

I modified autoexec.bat to put gcc\bin, perl\bin, etc in the path. I put the BDR util.zip programs in bin. I created a directory Dunnett with subdirectories src, r, man in c:/r/rw1040/src/library. I opened the dos window cd to c:/r/rw1040/src/gnuwin32 and type make libR.a it works and created a libR.a of 1.1 Mb Then I typed: Rcmd INSTALL c:/r/rw1040/src/library/Dunnett and got : make: Entering directory '/cygdrive/c/r/rw1040...

...d as part of the dependent variable values. Next thing I want to do with this dataset is to do multiple comparisons between each treatment (A, B, C, D, F, G) vs. vehicle at a given time point, say time=56 (the last time points) after adjusting the baseline imbalance. This seems to be done using Dunnet test. When I say "after adjusting baseline imbalance", I mean the comparisons should be done based on the difference between time=56 and time=0 (baseline), i.e. is there any difference in the change from baseline for treatment A (or B, C, D, F, G) vs. vehicle?. How can we test this? Wi...
