Okabe-Ito Palette
Description
palette_okabe_ito() is a wrapper around palette.colors() that returns the
Okabe-Ito palette in R 4.0.0 or greater. palette_okabe_ito() returns an
unnamed vector of colors for better use with ggplot2. Additionally, black is
the last color returned by palette_okabe_ito() when 9 colors are needed
instead of the first, as in palette.colors().
Usage
palette_okabe_ito(order = 1:9, alpha = NULL, recycle = FALSE)
Arguments
order |
A numeric vector, the order of the colors |
alpha |
an alpha-transparency level in the range [0,1] (0 means transparent and 1 means opaque). |
recycle |
logical indicating what happens in case |
Value
A character vector of hex codes
Examples
palette_okabe_ito()
palette_okabe_ito(order = c(2, 3, 5), alpha = 0.9)
Okabe-Ito Scales for ggplot2 and ggraph
Description
Discrete scales for the colorblind-friendly Okabe-Ito palette, including
color, fill, and edge_colour. See palette_okabe_ito for
details.
Usage
scale_okabe_ito(aesthetics, order = 1:9, alpha = 1, ...)
scale_colour_okabe_ito(aesthetics = "colour", order = 1:9, alpha = NULL, ...)
scale_color_okabe_ito(aesthetics = "colour", order = 1:9, alpha = NULL, ...)
scale_fill_okabe_ito(aesthetics = "fill", order = 1:9, alpha = NULL, ...)
scale_edge_colour_okabe_ito(
aesthetics = "edge_colour",
order = 1:9,
alpha = NULL,
...
)
scale_edge_color_okabe_ito(
aesthetics = "edge_colour",
order = 1:9,
alpha = NULL,
...
)
Arguments
aesthetics |
The names of the aesthetics that this scale works with. |
order |
A numeric vector, the order of the colors |
alpha |
an alpha-transparency level in the range [0,1] (0 means transparent and 1 means opaque). |
... |
Additonal arguments passed to |
Value
A ggplot or ggraph scale
Examples
library(ggplot2)
ggplot(mpg, aes(cty, hwy, color = class)) +
geom_point() +
scale_color_okabe_ito()
ggplot(mpg, aes(cty, hwy, color = factor(cyl))) +
geom_point(alpha = 0.7) +
scale_color_okabe_ito(name = "Cylinders", alpha = .9)
ggplot(mpg, aes(hwy, color = class, fill = class)) +
