Arguments

...

Arguments passed to ggplot2::continuous_scale().

reverse

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

range

A length-two numeric vector specifying the fraction of the scheme's color domain to keep.

aesthetics

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

discrete

A logical scalar: should the color scheme be used as a discrete scale?

Value

A continuous scale.

Details

Available schemes:

  • batlow

  • batlowW

  • batlowK

  • devon

  • lajolla

  • bamako

  • davos

  • bilbao

  • nuuk

  • oslo

  • grayC

  • hawaii

  • lapaz

  • tokyo

  • buda

  • acton

  • turku

  • imola

Interpolation

If more colors than defined are needed from a given scheme, the color coordinates are linearly interpolated to provide a continuous version of the scheme.

Note that the default color for NA can be overridden by passing a value to ggplot2::continuous_scale().
