Colour and fill scales from brain atlas palettes — scale_brain • ggseg

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.

Examples

if (FALSE) { # \dontrun{
library(ggplot2)
ggplot() +
  geom_brain(atlas = dk(), aes(fill = region), show.legend = FALSE) +
  scale_brain("dk")
} # }
