palette {base}

R Documentation

Set or View the Graphics Palette

Description

This function is used to view or manipulate the color palette which is used when a col= has a numeric index.

If value has length 1 it is taken to be the name of a built in color palette. If value has length greater than 1 it is assumed to contain a description of the colors which are to make up the new palette (either by name or by RGB levels).

If value is omitted or has length 0, no change is made the current palette.

Currently, the only built-in palette is "default".
