ciao all, my wishes for a marvelous 2006 to everybody! i am trying to run globaltest using two covariates on a exprset (15 saples x 22283 probesets, chipset affymetrix U133A). here is my command: globaltest(exprs.object, covar1 ~ covar2, cellcycle) where: > show(exprs.object) Expression Set (exprSet) with 22283 genes 15 samples phenoData object with 2 variables and 15 cases varLabels covar1: covar2: > covar1 [1] 1 1 1 1 1 1 1 1 1 1 0 0 0 0 0 > covar2 [1] 1 1 1 1 1 0 0 0 0 0 0 0 0 0 0 > class(covar1) [1] "numeric" > class(covar2) [1] "numeric" but what i get in output is: Error: Sample names in X inconsistent with sample names in Y. the phenoData is ok and if i try to run GlobalAncova() everything goes smoothly. where is the problem? thanks a lot for your kind help! greetings Dario -- Dario Greco Institute of Biotechnology - University of Helsinki Building Cultivator II P.O.Box 56 Viikinkaari 4 FIN-00014 Finland Office: +358 9 191 58951 Fax: +358 9 191 58952 Mobile: +358 44 023 5780 Lab WebPage: http://www.biocenter.helsinki.fi/bi/dna-microarray/ Personal WebPage: http://www.biocenter.helsinki.fi/bi/dna-microarray/dario.htm
