read.table with numeric row names
Thanks Yasir, this helps a lot. BTW, is there an R command to read just the first line of the file? Yasir Kaheil wrote
just do this: colnames(r)<-substr(colnames(r),2,nchar(colnames(r))) This will remove the X. Later when you want to use the headed to plot something, cast it as numeric: plot(colMeans(r)~as.numeric(colnames(r)))
