Voronoi object

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