## Diameter of a point set

### Description

Find an upper bound to the convex hull of a point set

### Usage

    inla.diameter(x, ...)

    ## Default S3 method:
    inla.diameter(x, manifold="", ...)
    ## S3 method for class 'inla.mesh'
    inla.diameter(x, ...)
    ## S3 method for class 'inla.mesh.segment'
    inla.diameter(x, ...)
    ## S3 method for class 'inla.mesh.lattice'
    inla.diameter(x, ...)
    ## S3 method for class 'inla.mesh.1d'
    inla.diameter(x, ...)

### Arguments

`x` | A point set as an n x d matrix, or an `inla.mesh` related object.
`manifold` | Character string specifying the manifold type. Default is to treat the point set with Euclidean R^d metrics. Use `manifold="S2"` for great circle distances on the unit sphere (this is set automatically for `inla.mesh` objects).
`...` | Additional parameters passed on to other methods.

### Value

A scalar, upper bound for the diameter of the convex hull of the point set.
