Glad to help! There are definitely enough colors, but they aren't all assigned numbers automatically: to see a list of built in ones, try colors()
You can always use a character string to specify a color as well -- but I think the easiest thing to do might be to use one of the palette functions like rainbow() to make a whole set of colors equally spaced throughout the rainbow. For production/optimized colors, look into the RColorBrewer package -- there's a somewhat large body of research on the best way to choose colors and that package will help automate that process.
