Fabio Crameri's batlowK Sequential Colour Scheme

## Usage

scale_colour_batlowK(
...,
reverse = FALSE,
range = c(0, 1),
discrete = FALSE,
aesthetics = "colour"
)

scale_color_batlowK(
...,
reverse = FALSE,
range = c(0, 1),
discrete = FALSE,
aesthetics = "colour"
)

scale_fill_batlowK(
...,
reverse = FALSE,
range = c(0, 1),
discrete = FALSE,
aesthetics = "fill"
)

scale_edge_colour_batlowK(
...,
reverse = FALSE,
range = c(0, 1),
discrete = FALSE,
aesthetics = "edge_colour"
)

scale_edge_color_batlowK(
...,
reverse = FALSE,
range = c(0, 1),
discrete = FALSE,
aesthetics = "edge_colour"
)

## 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.

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.

## Interpolation

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().
