create_smooth_gradient: Create a gradient

In muppetjones/remcolor: Defines color-blind friendly palettes and gradients.

Description

This function creates an RGB gradient based on a series of functions

Usage

create_smooth_gradient(R, G, B, incr = 255)

Arguments

R	A single parameter function for calculating the red value.
G	A single parameter function for calculating the green value.
B	A single parameter function for calculating the blue value.
incr	The number of steps to take in the gradient. Defaults to 255.

Examples

R <- function(x) {
 0.237 - 2.13 * x + 26.92 * x^2 - 65.5*x^3 + 63.5*x^4 - 22.36*x^5
}
G <- function(x) {
 ((0.572 + 1.524 * x - 1.811 * x^2)/(1 - 0.291 * x + 0.1574 * x^2))^2
}
B <- function(x) {
 1/(1.579 - 4.03*x + 12.92*x^2 - 31.4*x^3 + 48.6*x^4 - 23.36*x^5)
}
