makeVoronoiPolygons: Make Voronoi polygons from an INLA mesh and boundary

In SEEG-Oxford/seegMBG: Streamlined Model-Based Geostatistics Functions for the SEEG Research Group

Description

Create Voronoi polygons based on an inla.mesh object and an inla.mesh.segment object specifying the boundary (edge) of the Voronoi polygons.

Usage

makeVoronoiPolygons(mesh, boundary)

Arguments

mesh	an inla.mesh object.
boundary	an inla.mesh.segment object used to specify the Voronoi polygons boundary.

Value

An object of SpatialPolygons class.

Examples

# load packages
library(sp)
library(INLA)

# make a SpatialPolygons object
poly <- SpatialPolygons(list(
Polygons(list(Polygon(matrix(c(0, 11, -10, 10, -10, -5, 0, -5), ncol=2, byrow=TRUE))), ID=1)))

# make mesh
mesh <- inla.mesh.2d(
  boundary = inla.sp2segment(poly),
  max.edge = c(3,5))

# make voronoi polygons
v <- makeVoronoiPolygons(mesh, poly)
