carPalette: Set or Retrieve car Package Color Palette

Description

This function is used to set or retrieve colors to be used in car package graphics functions.

Usage

carPalette(palette)

Arguments

palette

if missing, returns the colors that will be used in car graphics; if present, the colors to be used in graphics will be set.

Value

Invisibly returns the previous value of the car palette.

Details

This function sets or returns the value of options(carPalette=pallete) that will be use in car graphics functions to determine colors. The default is c("black", "blue", "magenta", "cyan", "orange", "gray", "green3", "red")), which is nearly a permutation of the colors returned by the standard palette function that minimizes the use of red and green in the same graph, and that substitutes orange for the often hard to see yellow.
