spatstat.geom (version 2.2-0)

Geometrical Functionality of the 'spatstat' Family

Description

Defines types of spatial data such as point patterns, mainly in two dimensions, but also in higher dimensions. Provides class support, and functions for geometrical operations on spatial data, used in the 'spatstat' family of packages. Excludes spatial data on a linear network, which are covered by the separate package 'spatstat.linnet'.
