spatstat: An R Package for Analyzing Spatial Point Patterns

Adrian Baddeley, Rolf Turner

Main Article Content


spatstat is a package for analyzing spatial point pattern data. Its functionality includes exploratory data analysis, model-fitting, and simulation. It is designed to handle realistic datasets, including inhomogeneous point patterns, spatial sampling regions of arbitrary shape, extra covariate data, and "marks" attached to the points of the point pattern.

A unique feature of spatstat is its generic algorithm for fitting point process models to point pattern data. The interface to this algorithm is a function ppm that is strongly analogous to lm and glm.

This paper is a general description of spatstat and an introduction for new users.
