[S] Follow up: Woes of colors in S-plus

["Wright, Kevin" <WRIGHTKEVI@phibred.com>]

I had two replies to my lamentations.  Thanks to both.  One correction:  I
thought colors 17-30 were the same color.  Actually, those colors are subtly
varying shades which are used (I believe) for rendering surfaces among other
things.

John Wallace explained that the color numbers 17 and above are the first
color of the "Image Colors"

Anne York supplied a nice function for visualizing colors:

"swatch" <- function()
{
        plot(0:12, 0:12, col = 1, plot = F)
        for(i in 1:10) {
                for(j in 1:10) {
                        polygon(c(i, i, 1 + i, 1 + i), c(j, j + 1, j + 1,
j), 
                                col = 10 * (j - 1) + i)
                }
        }
}
