Cheysson color scales for ggplot2 — scale

Color and fill scales using Cheysson palettes from the Albums de Statistique Graphique.

Usage

scale_color_cheysson(
  palette = "1880_07",
  discrete = TRUE,
  reverse = FALSE,
  ...
)

scale_colour_cheysson(
  palette = "1880_07",
  discrete = TRUE,
  reverse = FALSE,
  ...
)

scale_fill_cheysson(palette = "1880_07", discrete = TRUE, reverse = FALSE, ...)

Arguments

palette: Name of palette (e.g., "1880_07") or palette type ("sequential", "diverging", "grouped", "category"). Default is "1880_07".
discrete: Whether to use a discrete (TRUE) or continuous (FALSE) scale. Default is TRUE.
reverse: Whether to reverse the palette colors. Default is FALSE.
...: Additional arguments passed to ggplot2 scale functions

Examples

if (FALSE) { # \dontrun{
library(ggplot2)

# Discrete color scale
ggplot(iris, aes(Sepal.Length, Sepal.Width, color = Species)) +
  geom_point() +
  scale_color_cheysson()

# Use a specific palette
ggplot(iris, aes(Sepal.Length, Sepal.Width, color = Species)) +
  geom_point() +
  scale_color_cheysson(palette = "1881_04")

# Use a sequential palette for continuous data
ggplot(iris, aes(Sepal.Length, Sepal.Width, color = Petal.Length)) +
  geom_point() +
  scale_color_cheysson(palette = "sequential", discrete = FALSE)

# Fill scale with category colors
ggplot(iris, aes(Species, Sepal.Width, fill = Species)) +
  geom_boxplot() +
  scale_fill_cheysson(palette = "category")
} # }
