Colour brain regions by your own values. Give `geom_brain()` an atlas like `dk()` and a data frame, and it matches your values to the right regions and lays out the brain views for you. No data? It just draws the atlas.
Usage
geom_brain(
mapping = aes(),
data = NULL,
atlas,
hemi = NULL,
view = NULL,
position = position_brain(),
context = TRUE,
show.legend = NA,
inherit.aes = TRUE,
...
)Arguments
- mapping
Set of aesthetic mappings created by [ggplot2::aes()].
- data
A data.frame containing variables to map. If `NULL`, the atlas is plotted without user data. Group it with [dplyr::group_by()] to facet.
- atlas
A `ggseg_atlas` object (e.g. `dk()`, `aseg()`, `tracula()`).
- hemi
Character vector of hemispheres to include (e.g. `"left"`, `"right"`). Defaults to all hemispheres in the atlas.
- view
Character vector of views to include, as recorded in the atlas data. For cortical atlases: `"lateral"`, `"medial"`. For subcortical/tract atlases: slice identifiers like `"axial_3"`. Defaults to all views.
- position
Position adjustment, either as a string or the result of a call to [position_brain()].
- context
Keep the rest of the brain as a soft grey backdrop (`TRUE`, the default), or show only the regions you're plotting (`FALSE`).
- show.legend
Logical. Should this layer be included in the legends?
- inherit.aes
Logical. If `FALSE`, overrides the default aesthetics rather than combining with them.
- ...
Additional arguments passed to [ggplot2::geom_polygon()].
