##### Integral of a Measure

Computes the integral (total value) of a measure over its domain.

##### Usage

```
## S3 method for class 'msr':
integral(f, domain=NULL, \dots)
```

##### Arguments

- f
- A signed measure or vector-valued measure (object of class
`"msr"`

). - domain
- Optional window specifying the domain of integration. Alternatively a tessellation.
- ...
- Ignored.

##### Details

The integral (total value of the measure over its domain) is calculated.

If `domain`

is a window (class `"owin"`

) then the integration
will be restricted to this window. If `domain`

is a tessellation
(class `"tess"`

) then the integral of `f`

in each
tile of `domain`

will be computed.

##### Value

- A numeric value (for a signed measure) or a vector of values (for a vector-valued measure).

##### Examples

```
fit <- ppm(cells, ~x)
rp <- residuals(fit)
integral(rp)
```
