crstn / voronoi.r
Created Jan 17, 2018
This is a small fix of Carson Farmer's Voronoi Polygons function (http://carsonfarmer.com/2009/09/voronoi-polygons-with-r/) which also copies the input points layer's CRS string over to the output polygons.
View voronoi.r
voronoipolygons = function(layer) {
require(deldir)
crds = layer@coords
z = deldir(crds[,1], crds[,2])
w = tile.list(z)
polys = vector(mode='list', length=length(w))
require(sp)
for (i in seq(along=polys)) {
pcrds = cbind(w[[i]]$x, w[[i]]$y)
pcrds = rbind(pcrds, pcrds[1,])
