%description
Topological data analysis (TDA) is a method of data analysis that uses
techniques from topology to analyze high-dimensional data. Here we
implement Mapper, an algorithm from this area developed by Singh, Mémoli
and Carlsson (2007) which generalizes the concept of a Reeb graph
<https://en.wikipedia.org/wiki/Reeb_graph>. The output graph is able to be
visualized in R using 'igraph' or using a free network analysis software
called 'Cytoscape', available for download from at
<https://cytoscape.org/>.
