voronoi: voronoi diagram and delauny triangles

Description

Get a voronoi diagram or delauny triangles for points, or nodes of lines or polygons

Usage

# S4 method for SpatVector
voronoi(x, bnd=NULL, tolerance=0, as.lines=FALSE, ...) 
# S4 method for SpatVector
delauny(x, tolerance=0, as.lines=FALSE, ...)

Arguments

x

SpatVector

bnd

SpatVector to set the outer boundary of the voronoi diagram

tolerance

numeric >= 0, snapping tolerance (0 is no snapping)

as.lines

logical. If TRUE, lines are returned without the outer boundary

...

additional arguments. None implemented

Value

SpatVector

Examples

# NOT RUN {
wkt <- c("MULTIPOLYGON ( ((40 40, 20 45, 45 30, 40 40)), 
  ((20 35, 10 30, 10 10, 30 5, 45 20, 20 35),(30 20, 20 15, 20 25, 30 20)))", 
  "POLYGON ((0 -5, 10 0, 10 -10, 0 -5))")
x <- vect(wkt)
v <- voronoi(x)
v

plot(v, lwd=2, col=rainbow(15))
lines(x, col="gray", lwd=2)
points(x)
# }
