Generic function for computing the intensity of a spatial dataset or spatial point process model.
intensity(X, ...)Usually a numeric value or vector.
A spatial dataset or a spatial point process model.
Further arguments depending on the class of X.

This is a generic function for computing the intensity of a spatial dataset
  or spatial point process model. There are methods for point patterns
  (objects of class "ppp") and fitted point process models
  (objects of class "ppm").
The empirical intensity of a dataset is the average density
  (the average amount of ‘stuff’ per unit area or volume).
  The empirical intensity of a point pattern is computed by the
  method intensity.ppp.
The theoretical intensity of a stochastic model is the expected density
  (expected  amount of ‘stuff’ per unit area or volume).
  The theoretical intensity of a fitted point process model is computed by the
  method intensity.ppm.
intensity.ppp,
  intensity.ppm.
