paleoTS-package {paleoTS} | R Documentation |
This package includes a variety of functions useful for analyzing evoltuionary time-series, particularly for paleontological data. The functions are useful for analyzing sequences in terms of statistical models, with three models implemented: directional evolution (modeled as a general random walk), unbiased random walks, and stasis. These analyses are outlined in Hunt (2006).
