I was looking at the Palmer Penguin dataset and noticed that it had two versions, one simplified and the other raw. While I understand why columns such as Comments were removed in the simplified version, I don't understand why two columns labeled Delta 15 N (o/oo) and Delta 13 C (o/oo) were not included in the simplified version.
I plan to test some clustering algorithms on the dataset and was wondering if including these two columns in my input would cause my tests to be inaccurate in some way.
