Extract Original Data from a Fitted Point Process Model

Description

Given a fitted point process model, this function extracts the original point pattern dataset to which the model was fitted.

Usage

  data.ppm(object)

Arguments

Details

An object of class "ppm" represents a point process model that has been fitted to data. It is typically produced by the model-fitting algorithm ppm. The object contains complete information about the original data point pattern to which the model was fitted. This function extracts the original data pattern.

See ppm.object for a list of all operations that can be performed on objects of class "ppm".

Value

A point pattern (object of class "ppp").
