Scales for plotting with WaSHI palettes

Source: R/scales.R
washi_scale.Rd

Provides compatibility with ggplot2.

Usage

washi_scale(
  palette = "color_blind",
  aesthetics = c("color", "fill"),
  alpha = 1,
  reverse = FALSE,
  discrete = TRUE,
  ...
)

Arguments

palette

Character name of palette in washi_pal. See names(washi_pal) for a list of available palettes.

aesthetics

Character string or vector of character strings listing the name(s) of the aesthetic(s) that this scale works with. Defaults to c("color", "fill"), which applies the palette to both the color and fill aesthetics at the same time.

alpha

Numeric transparency level of the color from 0 to 1. Default is 1 (not transparent).

reverse

Boolean indicating whether the palette should be reversed. Default is FALSE.

discrete

Boolean indicating whether color aesthetic is discrete or not. Default is TRUE.

...

Additional arguments passed to discrete_scale() or scale_color_gradientn(), used respectively when discrete is TRUE or FALSE

Value

A ScaleContinuous or ScaleDiscrete object that can be added to a ggplot object.
