title: Unable to use NRC lexicon in tidytext. Error in match.arg(lexicon) : 'arg' should be one of “afinn”, “bing”, “loughran”
body: <p>I am learning sentiment analysis in R using tidytext package. However, i am unable to set nrc as lexicon. Whenever i type get_sentiments ("nrc"), the above error is displayed. It says that lexicon coud only be "afinn", "bing" or "loughran". I tried updating the package (tidytext) and also installed 'syuzhet' package but still the problem exists. Please help!</p>
