问题
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" in tableau, he entered this
SCRIPT_STR('classify_polarity(.arg,algorithm="Bayes",verbose=TRUE) [,4]',
ATTR([CommentText]))

But for various reasons, i work with code, which specified here

And i don't know , on the basis of this code, what formula i must write in the calculate field. Please tell me, what i need write.
