tile.centroids: Compute centroids of Dirchlet (Voronoi) tiles

Description

Given a list of Dirichlet tiles, as produced by tile.list(), produces a data frame consisting of the centroids of those tiles.

Usage

tile.centroids(xxx)

Arguments

xxx

A list of the tiles (produced by tile.list()) in a Dirichlet tessellation of a set of planar points.

Value
