Hello I have a multivariate data frame giving various responses for several treatments. I would like to plot the relationship in the responses in a pairs plot with different symbols for the different treatments. In a regular plot I would have used 'matplot' or just added the new treatments with the 'points' function. But how to do it in a pairs plot? Thank you for your help Best Marion Dumas
