(synopsis "Density-based spatial clustering of applications with noise")
(description
"This package provides a fast reimplementation of several density-based
algorithms of the DBSCAN family. It includes the clustering algorithms DBSCAN
(density-based spatial clustering of applications with noise) and
@dfn{hierarchical DBSCAN} (HDBSCAN), the ordering algorithm @dfn{ordering
points to identify the clustering structure} (OPTICS), shared nearest neighbor
clustering, and the outlier detection algorithms @dfn{local outlier
factor} (LOF) and @dfn{global-local outlier score from hierarchies} (GLOSH).
The implementations use the kd-tree data structure for faster k-nearest
neighbor search. An R interface to fast kNN and fixed-radius NN search is
also provided.")
