volume.ellipsoid {cluster} | R Documentation

## Compute the Volume of Planar Object

### Description

Compute the volume of a planar object. This is a generic function and a method for `ellipsoid` objects.

### Usage

    ## S3 method for class 'ellipsoid'
    volume(object)

### Arguments

`object` | an R object the volume of which is wanted; for the `ellipsoid` method, an object of that class (see `ellipsoidhull` or the example below).

### Value

a number, the volume of the given `object`.

### See Also

`ellipsoidhull` for spanning ellipsoid computation.

### Examples

    ## example(ellipsoidhull) # which defines `ellipsoid' object <namefoo>

    myEl <- structure(list(cov = rbind(c(3,1),1:2), loc = c(0,0), d2 = 10),
                       class = "ellipsoid")
    volume(myEl)# i.e. "area" here (d = 2)
    myEl # also mentions the "volume"
