cerUB tutorial

Tutorial showcasing the cerUB package for R (cerUB).

This document shows how to use cerUB protocols to explore petrographic and compositional data. As an example, we provide the ‘amphorae’ dataset concerning wine Roman amphorae from sites in Catalonia, NE Spain. It is a live version of the Appendix C of an article published in Journal of Archaeological Science (see reference below).
