spatstat.geom (version 2.1-0)

spatstat.geom-package: The spatstat.geom Package

Description

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.

Arguments

Structure of the spatstat family

The original spatstat package grew to be very large, and CRAN requested that the package be divided into several sub-packages. So far the following sub-packages exist:

  • spatstat.utils containing basic utilities

  • spatstat.data containing datasets

  • spatstat.sparse containing linear algebra utilities

  • spatstat.geom containing geometrical objects and geometrical operations

  • spatstat.core containing the main functionality for statistical analysis of spatial data

  • spatstat.linnet containing functions for spatial data on a linear network

  • spatstat, which simply loads the other sub-packages listed above, and provides documentation.

When you install spatstat, these sub-packages are also installed. Then if you load the spatstat package by typing library(spatstat), the other sub-packages listed above will automatically be loaded or imported. For an overview of all the functions available in these sub-packages, see the help file for spatstat in the spatstat package,

Additionally there are several extension packages:

  • spatstat.gui for interactive graphics

  • spatstat.local for local likelihood (including geographically weighted regression)

  • spatstat.Knet for additional, computationally efficient code for linear networks

  • spatstat.sphere (under development) for spatial data on a sphere, including spatial data on the earth's surface

The extension packages must be installed separately and loaded explicitly if needed. They also have separate documentation.

Details

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-package spatstat.core.

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.
