Compute a vornoi tesselation of a map for a set of points.

voronoi(x, ext, eps = 1e-09)

Arguments

x

SpatialPoints* or two-column matrix or data.frame with x and y coordinates.

ext

Extent object.

eps

Numerical tolerance used in triangulation. See deldir.

Value

SpatialPolygonsDataFrame.

Examples

pts <- data.frame(x = c(1:2, 2), y = c(1, 1:2)) region <- raster::extent(c(0, 3, 0, 3)) sp::plot(voronoi(pts, region))
points(pts)
