The spatstat.geom package belongs to the spatstat family of packages. It defines classes of geometrical objects such as windows and point patterns, and provides functionality for geometrical operations on them.
spatstat is a family of R packages for the statistical analysis of spatial data. Its main focus is the analysis of spatial patterns of points in two-dimensional space.
The original spatstat package has now been split into several sub-packages.
This sub-package spatstat.geom defines the main classes of geometrical objects (such as windows, point patterns, line segment patterns, pixel images) and supports geometrical operations (such as shifting and rotating, measuring areas and distances, finding nearest neighbours in a point pattern).
Functions for performing statistical analysis and modelling are in the separate sub-packages spatstat.explore and spatstat.model.
Functions for linear networks are in the separate sub-package spatstat.linnet.
For an overview of all the functions available in the spatstat family, see the help file for spatstat in the spatstat package.
