intensity.ppx: 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

"intensity"(X, ...)

Arguments

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

Value

A single number or a numeric vector.

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.

Examples

Run this code
  X <- osteo$pts[[1]]
  intensity(X)
  marks(X) <- factor(sample(letters[1:3], npoints(X), replace=TRUE))
  intensity(X)
