Diverging colour gradient (continuous).
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
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)
pal <- div_gradient_pal(low = mnsl(complement("10R 4/6"), fix = TRUE))
image(r, col = pal(seq(0, 1, length.out = 100)))
