box3: Three-Dimensional Box

Description

Creates an object representing a three-dimensional box.

Usage

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

Value

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

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.

Examples

    box3()
    box3(c(0,10),c(0,10),c(0,5), unitname=c("metre","metres"))
    box3(c(-1,1))
