From spatstat v1.23-3 by Adrian Baddeley

Geometrical Calculations for Multi-Dimensional Box

Calculates the volume, diameter, shortest side, or eroded volume of a multi-dimensional box.

Keywords: spatial, math

Usage

## S3 method for class 'boxx':
diameter(x)
## S3 method for class 'boxx':
volume(x)
## S3 method for class 'boxx':
shortside(x)
## S3 method for class 'boxx':
eroded.volumes(x, r)

Arguments

x: Multi-dimensional box (object of class "boxx").
r: Numeric value or vector of numeric values for which eroded volumes should be calculated.

Details

diameter.boxx, volume.boxx and shortside.boxx compute the diameter, volume and shortest side length of the box.

eroded.volumes.boxx computes, for each entry r[i], the volume of the smaller box obtained by removing a slab of thickness r[i] from each face of the box. This smaller box is the subset consisting of points that lie at least r[i] units away from the boundary of the box.

Value

For diameter.boxx, shortside.boxx and volume.boxx, a single numeric value. For eroded.volumes.boxx, a numeric vector of the same length as r.

Examples

X <- boxx(c(0,10),c(0,10),c(0,5))
    diameter(X) 
    volume(X)
    shortside(X)
    hd <- shortside(X)/2
    eroded.volumes(X, seq(0,hd, length=10))
