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.
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 color 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.

Diverging Color Schemes

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.
