Here's an easy approach to start using R to generate insights from text data. I'll take you through the process of exploring themes in text data by visualizing the relationships between words, using a real dataset with user reviews of the Animal Crossing game. To do this, we'll use R, the tidytext package, and the ggraph package. This is an intro to the basics of text analysis in R.
