EloRating for dominance ranks

Hi! I need to estimate mangabeys ranks from raw data that report the dates, the time, the winner, the loser, and the intensity of the interactions (I also have draw data but I do not need to consider them). I am stuck with the code I found online and I also have no clue of how to get the ranks out of the eigenvalues. Can anyone help me with EloRating code in R?
