redWhiteGreen: Red-white-green color sequence

In WGCNA: Weighted Correlation Network Analysis

Red-white-green color sequence

Description

Generate a red-white-green color sequence of a given length.

Usage

redWhiteGreen(n, gamma = 1)

Arguments

n	number of colors to be returned
gamma	color correction power

Details

The function returns a color vector that starts with pure green, gradually turns into white and then to red. The power gamma can be used to control the behaviour of the quarter- and three quarter-values (between red and white, and white and green, respectively). Higher powers will make the mid-colors more white, while lower powers will make the colors more saturated, respectively.

Value

A vector of colors of length n.
