R: Voronoi object

voronoi {interp} | R Documentation

## Voronoi object

### Description

A `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`.
