Calculate the concordex coefficient

Bioconductor version: Development (3.20)

Many analysis workflows include approximation of a nearest neighbors graph followed by clustering of the graph structure. The concordex coefficient estimates the concordance between the graph and clustering results. The package 'concordexR' is an R implementation of the original concordex Python-based command line tool.
