Here is my R Code x<-1:20000 y<-2:141 data.matrix<-data.matrix(data[,y])#create data.matrix variableprobe<-apply(data.matrix[x,],1,var) variableprobe #output variance across probesets hist(variableprobe) #displaying histogram of variableprobe write.table(cbind(data[1], Variance=apply(data[,y],1,var)),file='c://variance.csv') #export as a .csv file.
Output in Excel all in 1 column. ProbeID "Variance" 1 "224588_at" 21.5825745738848 How do i separate them so that i can have three columns ProbeID Variance 1 224588_at 21.582..... thanks, Kei -- View this message in context: http://www.nabble.com/R-data-Export-to-Excel-tp15796903p15796903.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
