Hi D, Try this: T <- rep(c(rep(1, nrow(M)), rep(-1, nrow(M))), ncol(M)/2) Ana ---- Mensaje Original ---- De: spam56 at gto.net Para: bioconductor at stat.math.ethz.ch Asunto: RE: [BioC] Multiply dye-swaps Fecha: Thu, 6 Sep 2007 12:41:30 -0400 >Hi all, > >I have a simple problem that I can't seem to figure out.
