Introduction to Text Analysis in R

This R tutorial provides a basic introduction to one of the easier forms of text analysis to learn -- lexicon-based sentiment analysis. This tutorial is inspired by Silge and Robinson's "Text Mining in R: A Tidy Approach," which you can find here: https://www.tidytextmining.com/. March 28, 2022: Due to changes in tidytext package, the following steps need to be augmented/altered: + First, when installing the tidytext package, be sure to also install the stopwords package; doing so will allow you to use the get_stopwords function from tidytext. install.packages("stopwords") + To access the AFINN dictionary, you will need to install the textdata package. install.packages("textdata") + The get_sentiments function from tidytext now labels the sentiment score column/variable as value, whereas previously it defaulted to score. Thus, all references made to a score variable in the video tutorial should now be replaced with value. For a conceptual overview of text analysis, please see the following video:    • Text Analysis  .
