First you should do your best to forget that you ever saw the command "par(new=T)", rip that page out of any book you saw it in, blacklist any webpage etc. In general (as you see) it causes more problems than it solves.
Now to do what you want there are a couple of options, one of the simplest is to use the lines function: d1 <- density(x1) d2 <- density(x2) plot(d1, xlab='', col='red',main='', ylim=range(d1$y,d2$y), xlim=range(d1$x,d2$x) ) lines(d2, col='blue') Other options include the matplot function or tools in the lattice and ggplot2 packages.
