inla.diameter {INLA}R Documentation

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.
