colour mapping.
Usage
scale_brain_manual(
palette,
na.value = "grey",
...,
aesthetics = c("fill", "colour", "color")
)
scale_colour_brain_manual(...)
scale_color_brain_manual(...)
scale_fill_brain_manual(...)
Arguments

Named character vector mapping region names to colours.
- na.value
Colour for `NA` entries (default: `"grey"`).

Additional arguments (unused).

Which aesthetic to scale: `"fill"`, `"colour"`, or
`"color"`.
Value
A ggplot2 scale object.
Examples
library(ggplot2)
pal <- c("insula" = "red", "precentral" = "blue")
ggplot() +
geom_brain(atlas = dk(), aes(fill = region), show.legend = FALSE) +
scale_fill_brain_manual(palette = pal)
