DOYPAColors (version 0.0.2)

scale_color_doypa: Color scale for ggplot2 with DOYPAColors color palettes

Description

This function sets the color scale for ggplot2 using DOYPAColors color palettes, allowing you to apply these palettes to both discrete and continuous data.

Usage

scale_color_doypa(
  palette = NULL,
  n = NULL,
  reverse = FALSE,
  gradient = FALSE,
  discrete = FALSE,
  type = "all",
  colorblind = FALSE,
  ...
)

Value

A `ggplot2` color scale suitable for adding to a `ggplot2` object to control color aesthetics.

Arguments

palette

A character string specifying the name of the palette to use. If `NULL`, a random palette will be selected.

n

Number of colors needed. If `NULL`, it will default to the number of levels for discrete scales or to a continuous gradient for continuous scales.

reverse

A logical value indicating whether to reverse the order of colors in the palette. Default is `FALSE`.

gradient

A logical value indicating whether to interpolate colors as a gradient of `n` colors between the first and last colors of the palette. If `FALSE`, returns the first `n` colors of the palette.

discrete

Boolean indicating whether to generate a discrete or continuous palette (default: continuous).

type

A character string specifying the type of palettes to select from: "all", "seq" (sequential), "div" (diverging), or "qual" (qualitative). Default is "all".

colorblind

A logical value indicating whether to restrict the palette to colorblind-friendly options. Default is `FALSE`.

...

Additional parameters passed to ggplot2's `scale_color_*` functions.

Examples

library(ggplot2)

# Discrete data
data(iris)
disc <- ggplot(iris, aes(x = Petal.Width, y = Petal.Length, color = Species)) +
  geom_point() + theme_classic()
disc <- disc + scale_color_doypa(palette = "buzz", discrete = TRUE)
print(disc)

# Continuous data
cont <- ggplot(iris, aes(x = Petal.Width, y = Petal.Length, color = Sepal.Length)) +
  geom_point() + theme_classic()
cont <- cont + scale_color_doypa(palette = "buzz")
print(cont)

# Colorblind-friendly palette
disc_colorblind <- ggplot(iris, aes(x = Petal.Width, y = Petal.Length, color = Species)) +
  geom_point() + theme_classic()
disc_colorblind <- disc_colorblind + scale_color_doypa(colorblind = TRUE, discrete = TRUE)
print(disc_colorblind)
