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This package is for teaching purposes only: some datasets may be outdated.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