is.ppm

Checks whether its argument is a fitted point process model
  (object of class <code>"ppm"</code>).

spatial

A package for analysing spatial data, mainly Spatial Point
        Patterns, including multitype/marked points and spatial
        covariates, in any two-dimensional spatial region. Contains
        functions for plotting spatial data, exploratory data analysis,
        model-fitting, simulation, spatial sampling, model diagnostics,
        and formal inference. Data types include point patterns, line
        segment patterns, spatial windows, and pixel images. Point
        process models can be fitted to point pattern data. Cluster
        type models are fitted by the method of minimum contrast. Very
        general Gibbs point process models can be fitted to point
        pattern data using a function ppm similar to lm or glm. Models
        may include dependence on covariates, interpoint interaction
        and dependence on marks. Fitted models can be simulated
        automatically. Also provides facilities for formal inference
        (such as chi-squared tests) and model diagnostics (including
        simulation envelopes, residuals, residual plots and Q-Q plots).
