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.

Value

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

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.
