ggplot2 — scale_tol_diverging" />

Provides diverging colour scales from Paul Tol's Colour Schemes.

scale_colour_sunset(..., reverse = FALSE, midpoint = 0,
  aesthetics = "colour")

scale_color_sunset(..., reverse = FALSE, midpoint = 0,
  aesthetics = "colour")

scale_fill_sunset(..., reverse = FALSE, midpoint = 0,
  aesthetics = "fill")

scale_colour_BuRd(..., reverse = FALSE, midpoint = 0,
  aesthetics = "colour")

scale_color_BuRd(..., reverse = FALSE, midpoint = 0,
  aesthetics = "colour")

scale_fill_BuRd(..., reverse = FALSE, midpoint = 0,
  aesthetics = "fill")

scale_colour_PRGn(..., reverse = FALSE, midpoint = 0,
  aesthetics = "colour")

scale_color_PRGn(..., reverse = FALSE, midpoint = 0,
  aesthetics = "colour")

scale_fill_PRGn(..., reverse = FALSE, midpoint = 0,
  aesthetics = "fill")

Arguments

...

Arguments passed to continuous_scale.

reverse

A logical scalar. Should the resulting vector of colours be reversed?

midpoint

A length-one numeric vector giving the midpoint (in data value) of the diverging scale. Defaults to 0.

aesthetics

A character string or vector of character strings listing the name(s) of the aesthetic(s) that this scale works with.

Value

A continuous scale.

Details

If more colours than defined are needed from a given scheme, the colour coordinates are linearly interpolated to provide a continuous version of the scheme. Note that the default colour for NA can be overridden by passing a value to continuous_scale.
