Hello, I have a list with gene names, fold changes (=expression level) and chromosomes.
Names fold change chromosome hz 1.5 2 If I plot fold change versus chromosome (or vice versa): plot (ch, fc) I see only the chromosomes with numbers but not those with letter (x and y). What can I do? A second question: How can I add a single line in that plot at a certain y-level. Thanks Hermann [[alternative HTML version deleted]] ______________________________________________ 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.
