ggseg_data_cortical: Create cortical atlas data

Description

Creates a data object for cortical brain atlases. Cortical atlases use vertex indices that map regions to vertices on a shared brain surface mesh (e.g., fsaverage5).

Usage

ggseg_data_cortical(sf = NULL, vertices = NULL)
brain_data_cortical(sf = NULL, vertices = NULL)

Value

An object of class c("ggseg_data_cortical", "ggseg_atlas_data")

Arguments

sf

sf data.frame with columns label, view, geometry for 2D rendering. Optional but required for ggseg plotting.

vertices

data.frame with columns label and vertices (list-column of integer vectors). Each vector contains vertex indices for that region.

Examples

data <- ggseg_data_cortical(
  vertices = data.frame(
    label = c("bankssts", "caudalanteriorcingulate"),
    vertices = I(list(c(1L, 2L, 3L), c(4L, 5L, 6L)))
  )
)
