Needs fix

[Nic-Nic]

Kept the changes implemented by the user @diegommcc in a separate branch (3 commits in total) and reset them from master branch. The reason behind this is that those changes broke the package and its installation, causing trouble to users and other developers that have OmnipathR as a dependency. Please, be so kind as to fix the bugs and make sure everything works as intended before merging to master.
