Hi all, I'm trying to combine two MALists, named RGAmodel and RGBmodel, using rbind and am running into the following problem: > rbind(RGAmodel, RGBmodel) Error in match.names(clabs, names(xi)) : names don't match previous names: Name In addition: Warning message: longer object length is not a multiple of shorter object length in: clabs == nmi I checked that the names were the same for each object and that the classes and dimensions match: > names(RGAmodel) [1] "weights" "targets" "genes" "source" "printer" [6] "genesStatus" "M" "A" > names(RGBmodel) [1] "weights" "targets" "genes" "source" "printer" [6] "genesStatus" "M" "A" > class(RGAmodel) [1] "MAList" attr(,"package") [1] "limma" > class(RGBmodel) [1] "MAList" attr(,"package") [1] "limma" > dim(RGAmodel) [1] 32448 32 > dim(RGBmodel) [1] 32448 32 What am I doing wrong? I'm using R2.3.0 and Bioconductor 1.7 Thanks, Matt -- Matt Scholz Senior Research Specialist Department of Plant Sciences University of Arizona (520) 621-1695

Please ignore this sentence is my previous post -- rbinding doesn't actually work either way around if data.frames have different columns. Gordon
