It's best to include a small example of what you have done so far, and what you want to further do. Actual R code with a small sample dataset is great.

Most base graphics functions like point have a grid equivalent. In this case, use grid.points.


                panel = function(...) {
                  grid.points(.1, .1, pch = 2)

I found the Lattice book and the "R Graphics" book invaluable, both are worth getting. mailing list PLEASE do read the posting guide and provide commented, minimal, self-contained, reproducible code. Received on Wed 31 Mar 2010 - 19:56:10 GMT
