ggplot2 Colour Scale from an ltc Palette — scale_colour

Colours the colour aesthetic with an ltc palette, the way scale_colour_viridis() does. Set discrete = FALSE for a continuous scale. scale_color_ltc() is the same function under the US spelling.

Usage

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

scale_color_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_colour_gradientn() when discrete = FALSE.

Value

A ggplot2 scale, to add to a plot.

Examples

library(ggplot2)

ggplot(mtcars, aes(wt, mpg, colour = factor(cyl))) +
  geom_point(size = 3) +
  scale_colour_ltc(alger)
