      Hello,could you help me. I saw on youtube the video about sentiment analysis in R, and the man showed how integrate R in Tableau, but he used another package , namely "sentiment", it does not suit me. And he used classify _ function from sentiment package and when he wrote formula in "calculate field", he entered this

      SCRIPT_STR('classify_polarity(.arg,algorithm="Bayes",verbose=TRUE) [,4]',

      ATTR([CommentText]))
