If you already have this as a data frame or matrix then others have already mentioned matplot. If you are looking for a quick way to get the data into that form in the first place without manually padding it out with NAs then you could represent them as time series and cbind them. Assuming regularly spaced time series you can use ts: Y1 <- ts(c(1,3,5), start = 1) Y2 <- ts(c(7,9,11), start = 4) Y3 <- ts(c(13,15), start = 7) Y <- cbind(Y1, Y2, Y3) plot(Y, plot.type = "single", col = rainbow(3)) # or matplot(1:8, Y) ______________________________________________ [EMAIL PROTECTED] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
