ggplot2 Fill Scale from an ltc Palette — scale_fill_ltc • ltc

Colours the fill aesthetic with an ltc palette, the way scale_fill_viridis() does. Set discrete = FALSE for a continuous scale.

Usage

scale_fill_ltc(name, discrete = TRUE, direction = 1, ...)

Arguments

name: Character or unquoted name. The name of the desired palette.
discrete: TRUE for a discrete scale, FALSE for a continuous one.
direction: 1 keeps the palette order, -1 reverses it.
...: Passed on to ggplot2::discrete_scale() when discrete = TRUE, or to ggplot2::scale_fill_gradientn() when discrete = FALSE.

Value

A ggplot2 scale, to add to a plot.

Examples

library(ggplot2)

# discrete
ggplot(mtcars, aes(factor(cyl), mpg, fill = factor(cyl))) +
  geom_boxplot() +
  scale_fill_ltc(maya)


# continuous
ggplot(faithfuld, aes(waiting, eruptions, fill = density)) +
  geom_raster() +
  scale_fill_ltc(heatmap0, discrete = FALSE)
