Description Usage Arguments Value Author(s) See Also Examples
This function creates a Voronoi mosaic.
It creates first a Delaunay triangulation, determines the circumcircle centers of its triangles, and connects these points according to the neighbourhood relations between the triangles.
1 | voronoi.mosaic(x,y=NULL,duplicate="error")
|
x |
vector containing x coordinates of the data. If |
y |
vector containing y coordinates of the data. |
duplicate |
flag indicating how to handle duplicate elements.
Possible values are: |
