R: Diverging colour gradient (continous).

div_gradient_pal {scales} | R Documentation

## 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

    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)))
