Diameter bound for a geometric object

Description

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

Usage

fm_diameter(x, ...)

## S3 method for class 'matrix'
fm_diameter(x, manifold = NULL, ...)

## S3 method for class 'sf'
fm_diameter(x, ...)

## S3 method for class 'sfg'
fm_diameter(x, ...)

## S3 method for class 'sfc'
fm_diameter(x, ...)

## S3 method for class 'fm_lattice_2d'
fm_diameter(x, ...)

## S3 method for class 'fm_segm'
fm_diameter(x, ...)

## S3 method for class 'fm_mesh_2d'
fm_diameter(x, ...)

## S3 method for class 'fm_mesh_1d'
fm_diameter(x, ...)

## S3 method for class 'inla.mesh.1d'
fm_diameter(x, ...)

## S3 method for class 'inla.mesh.segment'
fm_diameter(x, ...)

## S3 method for class 'inla.mesh.lattice'
fm_diameter(x, ...)

## S3 method for class 'inla.mesh'
fm_diameter(x, ...)

Arguments

x	A point set as an n\times d matrix, or an fm_mesh_2d/⁠1d⁠/sf related object.
...	Additional parameters passed on to the submethods.
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 fm_fmesh_2d objects).

Value

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