In tesselle/khroma: Colour Schemes for Scientific Data Visualization

Fabio Crameri's oleron Multi-Sequential Color Scheme

Description

Fabio Crameri's oleron Multi-Sequential Color Scheme

Usage

scale_colour_oleron(
  ...,
  reverse = FALSE,
  range = c(0, 1),
  midpoint = 0,
  aesthetics = "colour"
)

scale_color_oleron(
  ...,
  reverse = FALSE,
  range = c(0, 1),
  midpoint = 0,
  aesthetics = "colour"
)

scale_fill_oleron(
  ...,
  reverse = FALSE,
  range = c(0, 1),
  midpoint = 0,
  aesthetics = "fill"
)

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.
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 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().

volcan <- data.frame(
  x = rep(1:ncol(volcano), each = nrow(volcano)),
  y = rep(1:nrow(volcano), times = ncol(volcano)),
  z = as.numeric(volcano)
)
