spatstat is a family of R packages for analysing spatial point pattern data (and other kinds of spatial data). See the website www.spatstat.org or read the book.

This repository holds the current development version of spatstat.

For the most recent official release of spatstat, see the CRAN page.

Originally there was a single package called spatstat. It grew so large (150,000 lines of code) that CRAN required us to split it into pieces.

Almost all of the code in the original spatstat has been placed into a family of sub-packages:

Sub-package	CRAN page	GitHub repository	Description
spatstat.utils		here	Basic utilities
spatstat.data		here	Datasets
spatstat.sparse		here	Sparse arrays
spatstat.geom		here	Spatial data classes; geometrical operations
spatstat.core		here	Data analysis and modelling of spatial data
spatstat.linnet		here	Spatial analysis on a linear network
spatstat		This repo	Umbrella package

There still exists a package called spatstat, which is now an umbrella package that requires all the sub-packages listed above. When you install the new spatstat, all the sub-packages listed above will be installed. When you load the spatstat package in an R session, all the sub-packages listed above will be loaded or imported.

Additionally there are extension packages which contain additional 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		here	Graphical interface
spatstat.Knet		here	linear networks
spatstat.local		here	Local (geographically weighted) models
spatstat.sphere	Not yet published	here	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.
