Deprecated sf brain-view layout — position_brain

The sf rendering path is deprecated. position_brain_sf() returns the legacy PositionBrain ggproto for use with geom_brain_sf(). For new code, use position_brain() (the polygon default), or convert the atlas with as_sf_atlas() and use ggplot2::geom_sf() directly.

Usage

position_brain_sf(
  position = "horizontal",
  nrow = NULL,
  ncol = NULL,
  views = NULL
)

Arguments

position: Formula describing the rows ~ columns organisation for cortical atlases (e.g., hemi ~ view). For subcortical/tract atlases, can be "horizontal", "vertical", or a formula with type ~ . where type is extracted from view names like "axial_1" -> "axial".
nrow: Number of rows for grid layout. If NULL (default), calculated automatically. Only used for subcortical/tract atlases when position is not a formula.
ncol: Number of columns for grid layout. If NULL (default), calculated automatically. Only used for subcortical/tract atlases when position is not a formula.
views: Character vector specifying which views to include and their order. If NULL (default), all views are included in their original order. Only applies to subcortical/tract atlases.

Value

A PositionBrain ggproto object.
