Create the “dividing chain” of the Dirchlet tesselation
of a given set of points having distinguishing (categorical)
“weights”. This dividing chain consists of those edges
of Dirichlet tiles which separate points having different values
of the given weights.
Usage
# S3 method for default
divchain(x, y, z, ...)
Arguments
x,y
These provide the coordinates of the set of points being
tesselated. Argument x may be a data frame or a
list, in particular one of class ppp. (See the
spatstat package.)
For a full description see the discussion of these arguments in the
help for deldir().
z
A factor specifying “auxiliary” values or
“weights” If this argument is left NULL then it
is extracted, if possible, from the components of x.
See deldir() for further details.
…
Other arguments to be passed to deldir.
Value
An object of class divchain. See
divchain.deldir() for details.
