%description
An R interface to the Leiden algorithm, an iterative community detection
algorithm on networks. The algorithm is designed to converge to a
partition in which all subsets of all communities are locally optimally
assigned, yielding communities guaranteed to be connected. The
implementation proves to be fast, scales well, and can be run on graphs of
millions of nodes (as long as they can fit in memory). The original
implementation was constructed as a python interface "leidenalg" found
here: <https://github.com/vtraag/leidenalg>. The algorithm was originally
described in Traag, V.A., Waltman, L. & van Eck, N.J. "From Louvain to
Leiden: guaranteeing well-connected communities". Sci Rep 9, 5233 (2019)
<doi:10.1038/s41598-019-41695-z>.
