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, which presents the dashboard available at https://www.uv.es/vivigui/AppEuroACB.html.

# Firstly, load BAwiR and other packages that will be used in the paper:
library(BAwiR) # 1.2
library(tidyverse) # 1.2.1
library(FSA) # 0.8.22
library(gridExtra) # 2.3
# Code for Figure 1:
# Load the data_app_acb file with the ACB games from the 1985-1986 season to the 2017-2018 season:
load(url("http://www.uv.es/vivigui/softw/data_app_acb.RData"))
title <- " Number of Spanish and foreign players along the ACB seasons \n Data from www.acb.com"
get_pop_pyramid(data_app_acb, title, "eng")
# Create the data with games and players' info, add the advanced stats and compute the total numbers:
