##### Linear Network of Delaunay Triangulation or Dirichlet Tessellation

Computes the edges of the Delaunay triangulation or Dirichlet tessellation of a point pattern, and returns the result as a linear network object.

##### Usage

`delaunayNetwork(X)`dirichletNetwork(X, …)

##### Arguments

- X
A point pattern (object of class

`"ppp"`

).- …
Arguments passed to

`as.linnet.psp`

##### Details

For `delaunayNetwork`

, points of `X`

which are neighbours
in the Delaunay triangulation
(see `delaunay`

) will be joined by a straight line.
The result will be returned as a linear network (object of class
`"linnet"`

).

For `dirichletNetwork`

, the Dirichlet tessellation is computed
(see `dirichlet`

) and the edges of the
tiles of the tessellation are extracted. This is converted to a linear
network using `as.linnet.psp`

.

##### Value

Linear network (object of class `"linnet"`

)
or `NULL`

.

##### Examples

```
# NOT RUN {
LE <- delaunayNetwork(cells)
LI <- dirichletNetwork(cells)
# }
```
