value2Color: Translate a numerical value into a color

In jotsetung/GenomePlotR: Plotting data in genomic context

Description

Simple function to map numerical input values into colors.

Usage

value2Color(x, colramp = colorRampPalette(brewer.pal(11, "RdBu"))(255), min.x, max.x, color.centered = TRUE, force.range = FALSE)

Arguments

x	The value(s) that should be translated into corresponding colors.
colramp	The color ramp that represents the color space corresponding to the numerical input space.
min.x	Smallest value to be expected as an input.
max.x	Largest value to be expected as an input.
color.centered	Whether the color bar/palette should be centered, i.e. symmetric around the central value.
force.range	If true, any input value that is larger than max.x or smaller than min.x will be set to max.x or min.x respectively.

Value

A character (vector) with corresponding color(s).
