Color Names

Description:

     Returns the built-in color names which R knows about.

Usage:

     colors()
     colours()

Details:

     These color names can be used with a 'col=' specification in
     graphics functions.

     An even wider variety of colors can be created with primitives
     'rgb' and 'hsv' or the derived 'rainbow', 'heat.colors', etc.

Value:

     A character vector containing all the built-in color names.

See Also:

     'palette' for setting the 'palette' of colors for
     'par(col='_<num>_')'; 'rgb', 'hsv', 'hcl', 'gray'; 'rainbow' for a
     nice example; and 'heat.colors', 'topo.colors' for images.

     'col2rgb' for translating to RGB numbers and extended examples.

Examples:

     cl <- colors()
     length(cl); cl[1:20]
