Frequently Asked Questions About S-Plus
The .First function - what is it and why should you

Then, when you type help.start(), the
help menu will appear in a netscape window.
Creating Color Postscript plots
To create color postscript plots, you will need to
specify a color scheme using ps.options. for example,
ps.options(colors = ps.colors.rgb[c("black",
"CadetBlue", "LightSeaGreen", "LightSlateBlue", "red", "green", "blue",
"yellow", "khaki", "maroon"), ], background = ps.colors.rgb[c("white"),
puts black as the first color, cadet blue as the
second, light sea green as the third, etc., and white as the background.
So, when you use col=5 in a plot command, you will plot in red. To
see what colors are available, check /usr/openwin/lib/rgb.txt.
