That does not look like a matrix but a data frame. Do a class(dataname) to check.
It is much better to present the data in a useable format. Have a look at ?dput for a way to provide the data. However if we assulme your data is xx, this may do what you want if I understand you correcctly. xx1 <-data.frame( t(xx[, 2:6])) xx1[,5] <- names(xx[2:6]) names(xx1) <- c(letters[1:4], "Name") ggplot(xx1, aes(x=factor(Name), a)) + geom_point() John Kane Kingston ON Canada > -----Original Message----- > From: robinmje...@gmail.com > Sent: Sat, 12 May 2012 03:29:35 -0700 (PDT) > To: r-help@r-project.org > Subject: [R] ggplot simple question. > > I have a matrix like this > > Name 1 2 > 3 4 5 > NM_001039514 1.033557047 0.7469879518 0.9004524887 0.8613861386 > 0.7952499048 > NM_001039723 1.0759493671 1.2315789474 0.8666666667 1.1142857143 > 0.9428011471 > NM_001042605 0.9897435897 0.8870431894 1.1038062284 0.7407407407 > 0.744530664 > NM_001048207 1.0070422535 0.9319727891 0.9015151515 0.8296438884 > 0.7290217712 > > I want to plot each row in a single graph and then use multiplot to put > them > all together in a single graph. > How do you plot the rows? > > > -- > View this message in context: > http://r.789695.n4.nabble.com/ggplot-simple-question-tp4628640.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. ____________________________________________________________ GET FREE SMILEYS FOR YOUR IM & EMAIL - Learn more at http://www.inbox.com/smileys Works with AIM®, MSN® Messenger, Yahoo!® Messenger, ICQ®, Google Talk™ and most webmails ______________________________________________ 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.
