intensity.ppx: Intensity of a Multidimensional Space-Time Point Pattern

In spatstat.geom: Geometrical Functionality of the 'spatstat' Family

Intensity of a Multidimensional Space-Time Point Pattern

Description

Calculates the intensity of points in a multi-dimensional point pattern of class "ppx" or "pp3".

Usage

  ## S3 method for class 'ppx'
intensity(X, ...)

Arguments

X	Point pattern of class "ppx" or "pp3".
...	Ignored.

Details

This is a method for the generic function intensity. It computes the empirical intensity of a multi-dimensional point pattern (object of class "ppx" including "pp3"), i.e. the average density of points per unit volume.

If the point pattern is multitype, the intensities of the different types are computed separately.

Value

A single number or a numeric vector.
