[R] subscripts for panel.superpose in lattice

Hi, I am trying to superimpose (overlay) regression lines to scatter plots by groups with xyplot (dysfunctional code below). However, my call of panel.superpose breaks down because of the subscripts requirement. I tried to research the documentation and examples, but I cannot figure out how to

It may not help the original poster, but here's a solution based on what Greg said above: # Load plotrix library(plotrix) # Create a new layout to divide the graphics in 2, the first one (displaying the persp() graph) being 4 times larger than the second one (displying the legend)
