    Sentiment Analysis using Tableau & R - Error "could not find function"?

    Nathan Masters

      Hi All

       

      I have successfully followed all the required steps to install R and the required packages to perform sentiment analysis over text.

      Is anyone able to assist and advise what I am missing?

      Regards

      Nathan
