voronoi: Voronoi object

In tripack: Triangulation of Irregularly Spaced Data

Voronoi object

Description

An voronoi object is created with voronoi.mosaic

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 tri.
area	area of triangle i. area[i]=-1 indicates a removed triangle with area 0 at the border of the triangulation.
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.
