Hi. I have two vectors of gene expression for each of several days. I want to plot both vectors on the same plot for a visual representation of up versus down regulation. I've tried using add=T but that doesn't work. eg>plot(Day, gene1) >plot(Day, gene2, add=T)Any help would be appreciated. Iain
Try plot(Day, gene1) lines(Day, gene2) see ?lines for more details. Charles Annis, P.E.

Hi You can use e.g. plot - points construction plot(Day, gene1) points(Day, gene2, col=2) see ?points ?lines You also need to set appropriate y range by ylim argument to first plot. And if you used search facility in CRAN and asked it multiple plots on same x axis you would have got many other posibilities for your question.
