plot(r1, type = "n") points(r1, col = "red", pch = 19) ## see also ?lines points(r2, col = "blue", pch = 19) points(r3, col = "black", pch = 19) ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
