Create a Voronoi mosaic
This function creates a Voronoi mosaic.
It creates first a Delaunay triangulation, determines the circumcircle centers of its triangles, and connects these points according to the neighbourhood relations between the triangles.
voronoi.mosaic(x,y=NULL,duplicate="error")
x |
vector containing x coordinates of the data. If |
y |
vector containing y coordinates of the data. |
duplicate |
flag indicating how to handle duplicate elements.
Possible values are: |
An object of class voronoi.

# example from TRIPACK:
data(tritest)
tritest.vm<-voronoi.mosaic(tritest$x,tritest$y)
tritest.vm
# use a part of the quakes data set:
data(quakes)
quakes.part<-quakes[(quakes[,1]<=-17 & quakes[,1]>=-19.0 &
quakes[,2]<=182.0 & quakes[,2]>=180.0),]
quakes.vm<-voronoi.mosaic(quakes.part$lon, quakes.part$lat, duplicate="remove")
