ggplot2 colour and fill scales using ggpalettes — scale_colour

When discrete is NULL, categorical palettes use a discrete scale and sequential/diverging palettes use a continuous gradient.

Usage

scale_colour_ggpalette(
  name = "meadow",
  discrete = NULL,
  binned = FALSE,
  alpha = 1,
  direction = 1,
  space = c("Lab", "rgb"),
  ...
)

scale_color_ggpalette(
  name = "meadow",
  discrete = NULL,
  binned = FALSE,
  alpha = 1,
  direction = 1,
  space = c("Lab", "rgb"),
  ...
)

scale_fill_ggpalette(
  name = "meadow",
  discrete = NULL,
  binned = FALSE,
  alpha = 1,
  direction = 1,
  space = c("Lab", "rgb"),
  ...
)

Arguments

name: Palette name.
discrete: Use a discrete scale. NULL selects from palette type.
binned: Use a binned continuous scale.
alpha: Opacity between 0 and 1.
direction: Palette direction: 1 or -1.
space: Interpolation colour space.
...: Additional arguments passed to the ggplot2 scale.

Value

A ggplot2 scale object.

Examples

library(ggplot2)
ggplot(iris, aes(Sepal.Length, Sepal.Width, colour = Species)) +
  geom_point(size = 2) +
  scale_colour_ggpalette("meadow")
