Voronoi object

An voronoi object is created with {voronoi.mosaic } voronoi.mosaic,plot.voronoi

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]

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