pp3 {spatstat.geom}

Three Dimensional Point Pattern

Description

Create a three-dimensional point pattern

Usage

pp3(x, y, z, ..., marks=NULL)

Arguments

x, y, z

Numeric vectors of equal length, containing Cartesian coordinates of points in three-dimensional space.

...

Arguments passed to as.box3 to determine the three-dimensional box in which the points have been observed.

marks

Optional. Vector, data frame, or hyperframe of mark values associated with the points.

Details

An object of class "pp3" represents a pattern of points in three-dimensional space. The points are assumed to have been observed by exhaustively inspecting a three-dimensional rectangular box. The boundaries of the box are included as part of the dataset.

Value

Object of class "pp3" representing a three dimensional point pattern. Also belongs to class "ppx".
