Dear Anthony, You can use xlim in plot() to reverse the x-axis. For example,
x <- 1:10 y <- x plot(x, y, xlim=rev(range(x))) (I'm pretty sure, by the way, that this question has been asked before.) I hope this helps, John -------------------------------- John Fox Department of Sociology McMaster University Hamilton, Ontario Canada L8S 4M4 905-525-9140x23604 http://socserv.mcmaster.ca/jfox -------------------------------- > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of Anthony Pitts > Sent: Tuesday, November 22, 2005 3:04 PM > To: r-help@stat.math.ethz.ch > Subject: [R] graphing help > > Hello all, > > Does anyone know how to make R graph the x-axis in descending > order?
