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

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

X

A point pattern (object of class `"ppp"`

).

…

Arguments passed to `as.linnet.psp`

Linear network (object of class `"linnet"`

)
or `NULL`

.

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`

.
