Deprecated sf brain geom — geom_brain

The sf rendering path is deprecated. geom_brain_sf() renders an atlas via ggplot2::geom_sf() and coord_sf(). For new code, use geom_brain() (the polygon default), or convert the atlas with as_sf_atlas() and use ggplot2::geom_sf() directly for the full sf toolkit (labels, other sf layers).

Usage

geom_brain_sf(
  mapping = aes(),
  data = NULL,
  atlas,
  hemi = NULL,
  view = NULL,
  position = NULL,
  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. Add a facet with ggplot2::facet_wrap() to draw one brain per group.
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().
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().

Value

A list of ggplot2 layer and coord objects.

Examples

if (FALSE) { # \dontrun{
# Deprecated: prefer geom_brain(). Shown for reference only.
library(ggplot2)
