clusterkernel: Extract Cluster Offspring Kernel

Description

Given a cluster point process model, this command returns the probability density of the cluster offspring.

Usage

clusterkernel(model, …)
# S3 method for kppm
clusterkernel(model, …)
# S3 method for character
clusterkernel(model, …)

Arguments

model

Cluster model. Either a fitted cluster or Cox model (object of class "kppm"), or a character string specifying the type of cluster model.

…

Parameter values for the model, when model is a character string.

Value

A function in the R\ language with arguments x,y,….

Details

Given a specification of a cluster point process model, this command returns a function(x,y) giving the two-dimensional probability density of the cluster offspring points assuming a cluster parent located at the origin.
