discrete.color: Map numbers onto a palette

Description

The continuous interval defined by range is divided into bins of equal size. Each bin is mapped to a colour in the palette defined by pal. The values in x are then assigned to the bins and their corresponding colours are returned. Values outside the interval are assigned to the border bins.

Usage

discrete.color(x, range = range(x), pal = "GnRd")

Arguments

x

Continuous numbers.

range

The interval in x that will be mapped to the palette.

pal

Palette. Can be the name of a predefined palette, as returned by xterm.pal, or a vector of colour indices directly.

Value

Colour indices from pal corresponding to where in the range the values in x are.
