spatstat is a family of R packages for analysing spatial point pattern data (and other kinds of spatial data). It has extensive capabilities for exploratory analysis, statistical modelling, simulation and statistical inference.

See the website www.spatstat.org or read the book.

Originally there was a single package called spatstat. It grew so large that CRAN required us to split it into pieces.

The original spatstat has now been divided into a family of sub-packages:

Sub-package	CRAN page	GitHub repository	Description
spatstat.utils			Basic utilities
spatstat.data			Datasets
spatstat.univar			🆕 Univariate probability distributions 🦘
spatstat.sparse			Sparse arrays
spatstat.geom			Spatial data classes; geometrical operations
spatstat.random			Generation of random patterns
spatstat.explore			Exploratory Data Analysis of spatial data
spatstat.model			Parametric modelling and formal inference for spatial data
spatstat.linnet			Spatial analysis on a linear network
spatstat			Umbrella package

Click the green badge to visit the CRAN page which contains the current release of each sub-package. Click the blue badge to visit the GitHub repository for the current development version of the sub-package.

There still exists a package called spatstat, which is now an umbrella package that requires all the sub-packages listed above.

You can install and load the new spatstat family in virtually the same way as you would previously have installed and loaded the old spatstat package. When you install the new umbrella package spatstat, all the sub-packages listed above will be installed. When you load the new umbrella spatstat package in an R session, all the sub-packages listed above will be loaded or imported.

Additionally there are extension packages which contain more functionality. These packages are not automatically installed or loaded; the user must do that if these extra features are desired.

Extension package	CRAN page	GitHub repository	Description
spatstat.gui			Graphical interface
spatstat.Knet			linear networks
spatstat.local			Local (geographically weighted) models
spatstat.sphere	Not yet published		Spherical data

The pink box marked spatstat contains all the code that will be installed when you install the spatstat umbrella package, and loaded or imported when you load the spatstat umbrella package.

The blue boxes are extension packages which must be installed and loaded separately.

spatstat is the result of 30 years of software development and contains over 180,000 lines of code. It is still under development, motivated by the needs of researchers in many fields, and driven by innovations in statistical science. We welcome contributions of code, and suggestions for improvements.
