##### Extract Original Data from a Fitted Point Process Model

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

- object
- fitted point process model (an object of class
`"ppm"`

).

##### 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"`

).
