This R script is meant to plot statistics based on Exodus Privacy reports issued before and after the GDPR day. The goal is to evaluate the impact of the GDPR on the number of trackers embedded in Android applications.

- the path where plots will be saved
- the name of your current study like Popular for popular applications, this name will be used as plot title

To execute this script, run the following command line:
Rscript --vanilla post_gdpr_stats.r $PWD Popular popular.txt
The app_list.js can be pasted in your browser JS console when you visit a Google Play store page listing applications (the popular category). The script with replace the content of the web page with the list of applications found in the page. Just copy and paste this list into a file and specify this file as the third parameter of the post_gdpr_stats.r script.
