4. Phylobase Extension- This package provides classes and methods which help read/write/manipulate branch-annotated phylogenetic trees (SIMMAP-format) and supports for a few other extra phylogenetic tree features (like tree weight).
6. Isolation Forest- This package implements an anomaly detection method that detects data-anomalies using binary trees. Using the property that anomalies are more susceptible to isolation, anomalies can be detected as data points which have short expected path lengths.
