ggplot2 color and fill scales for prakriti palettes

These functions plug prakriti palettes into ggplot2. By default the scale type (discrete vs. continuous) is chosen from the palette's metadata: qualitative palettes default to discrete; sequential and diverging palettes default to continuous. Override with discrete.

Usage

scale_color_prakriti(name, ..., discrete = NULL, direction = 1)

scale_colour_prakriti(name, ..., discrete = NULL, direction = 1)

scale_fill_prakriti(name, ..., discrete = NULL, direction = 1)

Arguments

name: Character. Name of the palette. See prakriti_names().
...: Additional arguments passed to the underlying ggplot2 scale constructor (ggplot2::discrete_scale(), ggplot2::scale_color_gradientn(), or ggplot2::scale_fill_gradientn()).
discrete: Logical or NULL. If NULL (default), inferred from the palette's type. Set TRUE to force discrete, FALSE for continuous.
direction: 1 (default) or -1 to reverse the palette order.

Value

A ggplot2 scale object.

Examples

# \donttest{
library(ggplot2)
ggplot(mtcars, aes(wt, mpg, color = factor(cyl))) +
  geom_point(size = 3) +
  scale_color_prakriti("valley_of_flowers")


ggplot(faithfuld, aes(waiting, eruptions, fill = density)) +
  geom_raster() +
  scale_fill_prakriti("himalaya")
