Datasets for Teaching Archaeology and Paleontology.

folio

Overview

Datasets for teaching quantitative approaches and modeling in archaeology and paleontology. This package provides several types of data related to broad topics (cultural evolution, radiocarbon dating, paleoenvironments, etc.), which can be used to illustrate statistical methods in the classroom (multivariate data analysis, compositional data analysis, diversity measurement, etc.).

This package is for teaching purposes only: some datasets may be outdated.

When using folio, you must cite the relevant publications for each dataset (see the documentation).

To cite folio in publications use:

  Frerebeau N (2024). _folio: Datasets for Teaching Archaeology and
  Paleontology_. Université Bordeaux Montaigne, Pessac, France.
  doi:10.5281/zenodo.4476182 <https://doi.org/10.5281/zenodo.4476182>,
  R package version 1.4.0, <https://packages.tesselle.org/folio/>.

A BibTeX entry for LaTeX users is
