Expands parcel-level values to a vertex-level vector using parcellation
labels.
Usage
parcels_to_vertices(parcel_data, labels, fill = NA_real_)
Arguments
- parcel_data
Named numeric vector of parcel values
(names match labels).
- labels
Integer vector of parcel labels. 0 and NA are medial wall.
- fill
Value for medial wall vertices (default: NA_real_).
