## Set or View the Graphics Palette

## Usage

    palette(value)

## Arguments

`value` | an optional character vector.

## 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"`.

## Value

The palette which was in effect. This is invisible unless the argument is omitted.

## See Also

`colors` for the vector of built-in ``named'' colors; `hsv`, `gray`, `rainbow`, `terrain.colors`,... to construct colors.

## Examples

    palette()           # obtain the current palette
    palette(rainbow(6)) # six color rainbow
    palette("default")  # reset back to the default
