Package: lumbermark Type: Package Title: Resistant Clustering via Chopping Up Mutual Reachability Minimum Spanning Trees Version: 0.9.0.9003 Date: 2026-07-01 Authors@R: person("Marek", "Gagolewski", role = c("aut", "cre", "cph"), email = "marek@gagolewski.com", comment = c(ORCID = "0000-0003-0637-6028") ) Description: Implements a fast and resistant divisive clustering algorithm which identifies a specified number of clusters: 'lumbermark' iteratively chops off sizeable limbs that are joined by protruding segments of a dataset's mutual reachability minimum spanning tree (Gagolewski, 2026 ). The use of a mutual reachability distance pulls peripheral points farther away from each other. It is a viable alternative to the 'HDBSCAN*'algorithm. When combined with the 'deadwood' package, it can act as an outlier detector. The 'Python' version of 'lumbermark' is available via 'PyPI'.
