Voronoi object
voronoi.RdA 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
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.
