div_gradient_pal: Diverging colour gradient (continous).

Description

Diverging colour gradient (continous).

Usage

div_gradient_pal(low = mnsl("10B 4/6"), mid = mnsl("N 8/0"), high = mnsl("10R 4/6"), space = "Lab")

Arguments

low
colour for low end of gradient.
mid
colour for mid point
high
colour for high end of gradient.
space
colour space in which to calculate gradient. Must be "Lab" - other values are deprecated.

Examples

Run this code
x <- seq(-1, 1, length.out = 100)
r <- sqrt(outer(x^2, x^2, "+"))
image(r, col = div_gradient_pal()(seq(0, 1, length.out = 12)))
image(r, col = div_gradient_pal()(seq(0, 1, length.out = 30)))
image(r, col = div_gradient_pal()(seq(0, 1, length.out = 100)))

library(munsell)
image(r, col = div_gradient_pal(low =
   mnsl(complement("10R 4/6", fix = TRUE)))(seq(0, 1, length = 100)))
