%description
An R to C/C++ interface that runs the Leiden community detection algorithm
to find a basic partition (). It runs the equivalent of the 'leidenalg'
find_partition() function, which is given in the 'leidenalg' distribution
file 'leiden/src/functions.py'. This package includes the required source
code files from the official 'leidenalg' distribution and functions from
the R 'igraph' package.  The 'leidenalg' distribution is available from
<https://github.com/vtraag/leidenalg/> and the R 'igraph' package is
available from <https://igraph.org/r/>. The Leiden algorithm is described
in the article by Traag et al. (2019) <doi:10.1038/s41598-019-41695-z>.
Leidenbase includes code from the packages: igraph version 0.9.8 with
license GPL (>= 2), leidenalg version 0.8.10 with license GPL 3.
