Dear All, In the moment i'm using the map and maptools package to read shapefiles and display the maps. I'm looking for the possibility to draw points (randomly positioned or positioned according to a grid) into the polygons instead of filling the polygons with colors.

Hi I am writing an R library. The documentation for one of my functions includes an example that I *know* works - simply cut and paste into R on either Windows and Linux and it works perfectly, no errors or warnings, nothing, nyet.
