Excellent! Thanks. -----Original Message----- From: Dimitris Rizopoulos [mailto:[EMAIL PROTECTED] Sent: 17 July 2007 13:40 To: Quin Wills Cc: r-help@stat.math.ethz.ch Subject: Re: [R] multiple rugs on a single plot
you could use different colours, e.g., x1 <- rnorm(100, -2.5, 1) x2 <- rnorm(100, 0, 1) x3 <- rnorm(100, 2.5, 1) x <- c(x1, x2, x3) plot(density(x)) rug(x1, col = "red") rug(x2, col = "black") rug(x3, col = "blue") or something like the following: plot(density(x)) len <- 0.005 ds <- 0.001 segments(x1, -1, x1, 0) segments(x2, 0 + ds, x2, len) segments(x3, len + ds, x3, 2*len) I hope it helps.
