scale_okabeito_discrete: Okabe and Ito's Discrete Color Scheme for ggplot2 and ggraph

Description

Provides the qualitative color scale from Okabe and Ito 2008.

Usage

scale_colour_okabeito(..., reverse = FALSE, aesthetics = "colour")
scale_color_okabeito(..., reverse = FALSE, aesthetics = "colour")
scale_fill_okabeito(..., reverse = FALSE, aesthetics = "fill")
scale_edge_colour_okabeito(..., reverse = FALSE, aesthetics = "edge_colour")
scale_edge_color_okabeito(..., reverse = FALSE, aesthetics = "edge_colour")
scale_edge_fill_okabeito(..., reverse = FALSE, aesthetics = "edge_fill")

Value

A discrete scale.

Arguments

...

Arguments passed to ggplot2::discrete_scale().

reverse

A logical scalar. Should the resulting vector of colors be reversed?

aesthetics

A character string or vector of character strings listing the name(s) of the aesthetic(s) that this scale works with.
