What can I do to help to get this merged?

@AndreiRegiani Thanks for the PR. Sorry for my delay. Two issues: I am wondering whether the license for the Spanish word list at https://github.com/jboscomendoza/rpubs/tree/master/sentimientos_afinn It is not immediately apparent to me. The other issue is the name of the data file. Is the file from tidytext?
