%description
The dependencies of CRAN packages can be analysed in a network fashion.
For each package we can obtain the packages that it depends, imports,
suggests, etc. By iterating this procedure over a number of packages, we
can build, visualise, and analyse the dependency network, enabling us to
have a bird's-eye view of the CRAN ecosystem. One aspect of interest is
the number of reverse dependencies of the packages, or equivalently the
in-degree distribution of the dependency network. This can be fitted by
the power law and/or an extreme value mixture distribution
<doi:10.48550/arXiv.2008.03073>, of which functions are provided.
