9.5.3 Books

The topic of handling text data in R is big enough to receive book-length treatments:

  • The book Handling Strings with R (by Gaston Sanchez) provides a comprehensive overview of string manipulation in R.

  • The book Text Mining with R (by Julia Silge and David Robinson) provides a guide to text analysis within a tidy data framework. It uses the tidytext package to format text into tables with one token of text per row and manipulate them to perform advanced tasks.
