circular_palette
Description
A helper function for circularizing color palettes.
Usage
circular_palette(n, pal_function=rainbow, invert=FALSE, ...)
Arguments
n |
Number of colors to output (must be divisible by 2) |
pal_function |
The base palette to circularize |
invert |
Whether to invert the palette See details. |
... |
Arguments passed to 'pal_function' |
Details
This function is useful when the color represents radial data. E.g. position on a sphere or circle. The 'invert' parameter reverses the order of circularization. E.g. if your circular palette would be red to blue to red, 'invert' changes this blue to red to blue.
Value
A circular color palette
Examples
colors <- circular_palette(n=1000, pal_function=rainbow)
t <- seq(0,2*pi, length.out=1000)
plot(sin(t), cos(t), col = colors, pch = 19)
