I handed in my TFG recently but the teacher asked me for some corrections that I don’t know how to do. I don’t know if you could help me with this. I attach the TFG, the content in R that I have used and the corrections. All the best Corrections: -In point 4, make a well-done correlation between the raw materials and a box diagram and reduce a little the material-by-material analysis that is very repetitive. – In point 5, take the analyzes that you had done before, not these new ones, and add some additional restriction and make your efficient frontier again.
