geos_voronoi_polygons

geos_voronoi_edges

These functions return one triangulation/diagram per feature as a
multi geometry. These functions are not vectorized along their parameters.

Provides an R API to the Open Source Geometry Engine
('GEOS') library (<https://libgeos.org/>) and a vector format
with which to efficiently store 'GEOS' geometries. High-performance functions
to extract information from, calculate relationships between, and
transform geometries are provided. Finally, facilities to import
and export geometry vectors to other spatial formats are provided.
