This repository contains the data collaboratively collected and prepared in the workshop "Cultural evolutionary tools for stone tool shape analysis: Geometric morphometrics and Bayesian phylogenetics" hosted at the Aarhus Institute for Advanced Studies, in Aarhus, Denmark in September 2022. The dataset present in the folder database contains outlines together with their associated metadata of 646 artefacts collected from eight different countries, spanning a timeframe of ~18.000 to 500 years BP. For further information, please refer to the Supplementary Informations.
After downloading, the results can be reproduced using CES_2022_workshop.Rproj and the existing folder structure. The required packages and their versions which have been used in this study are listed below and in the DESCRIPTION-file. All analyses and visualisations presented in this paper were prepared in R 4.2.1 under Ubuntu 18.04.5 LTS (64-bit).
The R code provides an example on how to load, inspect, and plot different aspects of the data. It requires the following R-packages: dplyr (>= 1.0.8), ggplot2 (>= 3.4.0), ggthemes (>= 4.2.4), magrittr (>= 2.0.2), Momocs (>= 1.3.0), outlineR (>= 0.1.0), raster (>= 3.5-15), readr (>= 2.1.2), remotes (>= 2.4.2), rgeos (>= 0.5-9), rworldmap (>= 1.3-6), sp (>= 1.4-6).
