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This package is for teaching purposes only: some datasets may be outdated.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*. UniversitÃ© Bordeaux Montaigne, Pessac, France. doi:10.5281/zenodo.4476182 https://doi.org/10.5281/zenodo.4476182, R package
version 1.5.0, https://packages.tesselle.org/folio/.

This package is a part of the tesselle project https://www.tesselle.org.

You can install the released version of **folio** from
CRAN with:

`install.packages("folio")`

And the development version from GitHub with:

```
# install.packages("remotes")
::install_github("tesselle/folio") remotes
```

```
