This document contains all the needed R code to reproduce the results described in the paper *A Web Application for Interactive Visualization of European Basketball Data* ([https://doi.org/10.1089/big.2018.0124](https://doi.org/10.1089/big.2018.0124){target="_blank"}), which presents the dashboard available at [https://www.uv.es/vivigui/AppEuroACB.html](https://www.uv.es/vivigui/AppEuroACB.html){target="_blank"}. This dashboard belongs to the platform available at [https://www.uv.es/vivigui/basketball_platform.html](https://www.uv.es/vivigui/basketball_platform.html){target="_blank"}.
