In the data storage section below you will find a link to our project Github repository storing the code files used to conduct the paper's statistical tests, models, and graphics. Here is a link to the Github repository: https://github.com/mrpargeter/Pargeter_et_al_handaxe_skill
You will also find the raw data files necessary to recreate the paper's statistical methods for use and integration with the code files. You can download these as a zip file (Pargeter_et_al_handaxe_data_files.zip). BE sure to place them in a folder you will call into the R code.
