Thank you Nikolaos Tziokas !

Ferran Oró Arán if you completed the code, share it here so others can find it. Also, when you do it, accept it as an answer. Thanks.

Nikolaos Tziokas at the end I ended up reading the file as a simple feature (SF), and using this package (sf) for the purpose of my research. This has been a better solution for what I aimed to do.

Thank you for reminding me
