This is a subset of the original spatstat package.
The original spatstat package is still available
at its CRAN page
or at the GitHub repository.
The original spatstat package is currently being split into
several sub-packages.
This package spatstat.core is one of the
sub-packages. It contains all the main user-level functions that perform
statistical analysis and modelling of spatial data,
with the exception of data on linear networks.
The reorganisation of the spatstat family is described
on the GitHub repository
baddstats/spatstat.
