##### Intensity of a Multidimensional Space-Time Point Pattern

Calculates the intensity of points in a multi-dimensional point
pattern of class `"ppx"`

or `"pp3"`

.

##### Usage

```
# S3 method for 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.

##### Examples

```
# NOT RUN {
X <- osteo$pts[[1]]
intensity(X)
marks(X) <- factor(sample(letters[1:3], npoints(X), replace=TRUE))
intensity(X)
# }
```
