This set of R scripts was designed to analyze the European Parliament votes through a multiplex network-based approach. See the bibliographic reference indicated in the readme file for more details. Our tool was applied to data representing the activity of the members of the European Parliament (MEPs) during the 7th term (from June 2009 to June 2014), as described in [AFL'19]. The raw data describing this activity were retrieved from the It's Your Parliament website. There were some minor issues with these data, which we had to correct: some MEPs were represented twice, some profiles were incomplete, the policy domains were not defined for all vote texts, etc. These cleaned data are available on FigShare (see readme file).
