## 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

`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"`).

     X <- data.ppm(fit)
     # 'X' is identical to 'cells'
