data.ppm: 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)

Value

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

Arguments

object

fitted point process model (an object of class "ppm").

Author

Adrian Baddeley and Rolf Turner .

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".

 fit <- ppm(cells, ~1, Strauss(r=0.1))
 X <- data.ppm(fit)
 # 'X' is identical to 'cells'
