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(tl)

Arguments

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

Value

A data frame with two columns named x and y. Each row of this data frame consitutes the centroid of one of the Dirichlet tiles.
