Deepayan is right, of course. Here's a simple example: t <- seq(0, 4*pi, length=500) x <- sin(t) y <- cos(t) z <- t library(lattice) cloud(z ~ x * y, type="l") HTH, Andy ______________________________________________ [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
