Dear Bioconductor developers, I am using multtest package to do some analysis. I am using the function mt.maxT/mt.minP to do some paired t-test. I email to ask how does the function recognize "paires" out of a classlabel like c(0,1,0,1,0,1,0,1,0,1,....,0,1). Does the package pair the first "0" with the first "1"? Much thanks and best regards, Anqi -- [[alternative HTML version deleted]]

Yes. You can sort of deduce this from the help page. So if you look at the help for mt.maxT you can see that the help for the classlabel argument states that 'The observations are ordered by block, and within each block, they are labeled using the integers 0 to k-1. ' In addition, there is an example # Permutation adjusted p-values for maxT procedure with paired t-statistics classlabel<-rep(c(0,1),19) mt.maxT(smallgd,classlabel,test="pairt") Best, Jim > > Much thanks and best regards, > Anqi > > > -- > > [[alternative HTML version deleted]] > > _______________________________________________ > Bioconductor mailing list > Bioconductor at stat.math.ethz.ch > https://stat.ethz.ch/mailman/listinfo/bioconductor > Search the archives: http://news.gmane.org/gmane.science.biology.informatics.conductor -- James W.
