The important files are the ones written in R, they should be ran sequentially (Part_1, Part_2, Part_3...), they were not put in the same single file, since each one has its own graphs and, most importantly, they build iteratively from each other, some produce new excel sheets that other ones will read, while some use data and results that were gathered in previous ones. Programation languages are also very prone to not be able to read and create files at the same time , in this case .csv, that's why they were built separately.
