Arguments

...

Arguments passed to ggplot2::continuous_scale().

reverse

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

range

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

midpoint

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

discrete

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

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 ggplot2::continuous_scale().

Available schemes:

  • broc

  • cork

  • vik

  • lisbon

  • tofino

  • berlin

  • roma

  • bam

  • vanimo
