Colour and fill scales from brain atlas palettes

Description

'r lifecycle::badge("deprecated")'

Atlas palettes are now applied automatically by [geom_brain()]. Use [scale_fill_brain_manual()] for custom palettes.

Usage

scale_brain(
  name = "dk",
  na.value = "grey",
  ...,
  aesthetics = c("fill", "colour", "color")
)

scale_colour_brain(name = "dk", na.value = "grey", ...)

scale_color_brain(name = "dk", na.value = "grey", ...)

scale_fill_brain(name = "dk", na.value = "grey", ...)

Arguments

name	String name of the atlas palette (e.g. '"dk"', '"aseg"').
na.value	Colour for 'NA' entries (default: '"grey"').
...	Additional arguments passed to [ggseg.formats::atlas_palette()].
aesthetics	Which aesthetic to scale: '"fill"', '"colour"', or '"color"'.

Value

A ggplot2 scale object.
