Arguments

col

degrees

A number between 0 and 360, denoting the amount of degrees the colors should be rotated. Defaults to 0.

Value

A colors object of the same length as col.

Details

The colors will be transformed to HCL color space (Hue-Chroma-Luminance) where the hue of the color will be rotated.

Examples

plot(clr_rotate(terrain.colors(10)))


plot(clr_rotate(terrain.colors(10), degrees = 90))


plot(clr_rotate(terrain.colors(10), degrees = 180))


plot(clr_rotate(rep("magenta", 11), degrees = seq(0, 360, length.out = 11)))
