Dear All, Is it possible to export transformed data from the lumi package? I want to use the data in another statistical program and export it from R as an .txt file. I've tried write.table command but it does not work on batch objects. I could export expression values by using temp <- exprs(lumi.T) but the file does not include gene names. The data I want to export has been produced like this (lumi version 1.10.2): smctarget <- 'H:/Geeniekspressio/Illumina_files/targetidsmc.txt' smctarget.lumi <- lumiR(smctarget, detectionTh=0.01, QC=TRUE, inputAnnotation=FALSE, checkDupId=FALSE, lib='lumiHumanAll') lumi.T <- lumiT(smctarget.lumi, method=c('log2'), ifPlot=TRUE) or with a command used to normalize the first data: lumiqtlog2.N <- lumiN(lumi.T, method='quantile', verbose=TRUE) What I would like to export is expression values from the object lumi.T or lumigtlog2.N. I would like the data to include the targetID names and the expression values after transformation or after transformation+normalization from each of the chips in the data. Could anybody help? Are there help pages available which address this issue? -Mervi [[alternative HTML version deleted]]
