scale_crameri_cyclic: Fabio Crameri's Cyclic Color Schemes for ggplot2 and ggraph

Description

Provides cyclic color scales from Fabio Crameri's Scientific colour.

Value

A continuous scale.

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?

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().
