Voronoi object

A voronoi object is created with voronoi.mosaic

Keywords
spatial
Arguments
x,y

x and y coordinates of nodes of the voronoi mosaic. Each node is a circumcircle center of some triangle from the Delaunay triangulation.

node

logical vector, indicating real nodes of the voronoi mosaic. These nodes are the centers of circumcircles of triangles with positive area of the delaunay triangulation.

If node[i]=FALSE, (c[i],x[i]) belongs to a triangle with area 0.

n1,n2,n3

indices of neighbour nodes. Negative indices indicate dummy points as neighbours.

tri

triangulation object, see triSht.

area

area of triangle \(i\).

ratio

aspect ratio (inscribed radius/circumradius) of triangle \(i\).

radius

circumradius of triangle i.

dummy.x,dummy.y

x and y coordinates of dummy points. They are used for plotting of unbounded tiles.

Note

This version of voronoi object is generated from the tri.mesh function from package interp. That's the only difference to voronoi objects generated with package tripack.
