R: Three-Dimensional Box

box3 {spatstat.geom} | R Documentation

## Three-Dimensional Box

### Description

Creates an object representing a three-dimensional box.

### Usage

    box3(xrange = c(0, 1), yrange = xrange, zrange = yrange, unitname = NULL)

### Arguments

`xrange, yrange, zrange` | Dimensions of the box in the x,y,z directions. Each of these arguments should be a numeric vector of length 2.
`unitname` | Optional. Name of the unit of length. See Details.

### Details

This function creates an object representing a three-dimensional rectangular parallelepiped (box) with sides parallel to the coordinate axes.

The object can be used to specify the domain of a three-dimensional point pattern (see `pp3`) and in various geometrical calculations (see `volume.box3`, `diameter.box3`, `eroded.volumes`).

The optional argument `unitname` specifies the name of the unit of length. See `unitname` for valid formats.

The function `as.box3` can be used to convert other kinds of data to this format.

### Value

An object of class `"box3"`. There is a print method for this class.
