You are running out of colors in your color map. A typical X server with 8 bits per pixel only has 256 different colors available at any time. Both Netscape and R will use up several of these colors. Do you know how many bitplanes you can make available for your X server? If you can change from 8 bits per pixel to 16 bits per pixel, that is by far the simplest thing to do. At 16 bits per pixel you can run "truecolor" with a 565 weighting (5 bits for red, 6 bits for green, and 5 bits for blue) and you don't have to mess with color maps. If not, try using emacs and ESS (Emacs Speaks Statistics), the emacs mode for running R (and S-PLUS and xlispstat and SAS and ...). The help facilities are integrated into ESS so you can display help pages without having to go through a browser.
