Hi, Input Format: excel file (XLS) Column 1: Gene ID (alphanumeric) Column 2 - 10 : (numeric data). inData = read.xls ( <fileName>) geneLabel = inData [ , 1] - column 1 stored in geneLabel tempData = inData [ , 2: 10] expValues = data.matrix (tempData) - convert frame into Matrix format expValues has the matrix format needed for analysis. I need to bind gene labels as . I have this data in geneLablel (extracted from data.frame) How do I convert this to a list so i can use rownames(expValues) <- ??????? thanks -- View this message in context: http://r.789695.n4.nabble.com/Frame-Column-to-List-conversion-tp4637341.html Sent from the R help mailing list archive at Nabble.com.
Frame Column to List (conversion)

Hello, Try using the vector geneLabel. You don't need to convert to list. rownames(expValues) <- geneLabel # if this doesn't work rownames(expValues) <- as.vector(geneLabel) But I really don't see a problem with the first. Have you tried it? Hope this helps, Rui Barradas Em 22-07-2012 03:04, biostat1 escreveu:

Hi, Try this: ?test1<-read.table(text=" Fkh2 0.141? 0.242? 0.342 ?Swi5 0.224? 0.342? 0.334 ?Sic1 0.652? 0.682? 0.182 ?",sep="",header=FALSE) ?test1 #??? V1??? V2??? V3???
