Analysis of Quaternary Science Data

Description

rioja: An R package for the analysis of Quaternary science data. Contains functions for constrained clustering, transfer functions, and plotting stratigraphic data.

Details

The rioja package contains a number of tools for analysing and visualising (bio)stratigraphic data and for developing palaeoecological transfer functions from a dataset of modern species counts and environmental measurements. Resulting models can be cross-validated using the crossval function, which allows internal cross-validation using leave-one-out, leave-n-out, bootstrapping or h-block cross-validation.
