spatstat is an R package for analyzing spatial point patterns. It provides tools for exploratory data analysis, model fitting, and simulation. The package handles complex datasets, including inhomogeneous point patterns, irregular sampling regions, extra covariate data, and marked points. A key feature is its generic algorithm for fitting point process models, analogous to lm and glm. spatstat supports various data types, including point patterns, windows, and pixel images. It includes functions for creating, manipulating, and plotting point patterns, as well as for exploratory data analysis and parametric model fitting. The package can simulate point process models and supports a wide range of statistical techniques for analyzing spatial point patterns. spatstat also provides tools for handling marked point patterns, multitype point patterns, and pixel images. The package includes functions for summary statistics, model fitting, and diagnostics, and is designed to handle real datasets with complex spatial structures.spatstat is an R package for analyzing spatial point patterns.
