scale_pattern_colour_brewer: Sequential, diverging and qualitative colour scales from colorbrewer.org

Description

The `brewer` scales provides sequential, diverging and qualitative colour schemes from ColorBrewer. These are particularly well suited to display discrete values on a map. See http://colorbrewer2.org for more information.

Usage

scale_pattern_colour_brewer(
  ...,
  type = "seq",
  palette = 1,
  direction = 1,
  aesthetics = "pattern_colour"
)
scale_pattern_fill_brewer(
  ...,
  type = "seq",
  palette = 1,
  direction = 1,
  aesthetics = "pattern_fill"
)
scale_pattern_fill2_brewer(
  ...,
  type = "seq",
  palette = 1,
  direction = 1,
  aesthetics = "pattern_fill2"
)
scale_pattern_colour_distiller(
  ...,
  type = "seq",
  palette = 1,
  direction = -1,
  values = NULL,
  space = "Lab",
  na.value = "grey50",
  guide = "colourbar",
  aesthetics = "pattern_colour"
)
scale_pattern_fill_distiller(
  ...,
  type = "seq",
  palette = 1,
  direction = -1,
  values = NULL,
  space = "Lab",
  na.value = "grey50",
  guide = "colourbar",
  aesthetics = "pattern_fill"
)
scale_pattern_fill2_distiller(
  ...,
  type = "seq",
  palette = 1,
  direction = -1,
  values = NULL,
  space = "Lab",
  na.value = "grey50",
  guide = "colourbar",
  aesthetics = "pattern_fill2"
)

Arguments

...

Other arguments passed on to [discrete_scale()], [continuous_scale()], or [binned_scale()], for `brewer`, `distiller`, and `fermenter` variants respectively, to control name, limits, breaks, labels and so forth.

palette

If a string, will use that named palette. If a number, will index into the list of palettes of appropriate `type`. The list of available palettes can found in the Palettes section.

direction, type, aesthetics, values, space, na.value, guide

See ggplot2::scale_colour_brewer for more information.

Palettes

The following palettes are available for use with these scales:

Diverging: BrBG, PiYG, PRGn, PuOr, RdBu, RdGy, RdYlBu, RdYlGn, Spectral
Qualitative: Accent, Dark2, Paired, Pastel1, Pastel2, Set1, Set2, Set3
Sequential: Blues, BuGn, BuPu, GnBu, Greens, Greys, Oranges, OrRd, PuBu, PuBuGn, PuRd, Purples, RdPu, Reds, YlGn, YlGnBu, YlOrBr, YlOrRd

Modify the palette through the `palette` arguement.

Details

The `brewer` scales were carefully designed and tested on discrete data. They were not designed to be extended to continuous data, but results often look good. Your mileage may vary.
