Excellent!

Hi I could only find some discussion on this wrt lattice graphics (which I'm not using). Apologies if I'm missing something obvious. I'd like to produce 3 rug plots under a kernel density plot for a population. The population is subdivided into 3 subpopulations, which I'd like the rug plots to highlight. Naturally, when I do 3 rug plots, they all plot over each other. I'd like 3 parallel rug plots along the x-axis. But how. Thanks in advance, Quin [[alternative HTML version deleted]]
