Leon.French@camh.caText Mining with R: A Tidy Approach by Julia Silge and David Robinson
This book/guide is available completely online (https://www.tidytextmining.com/index.html) and it offers a nice overview of popular topics in text mining (i.e., sentiment analysis, word frequencies, topic modelling) as well as how to carry out the analyses in R with examples.
An Introduction to Text Processing and Analysis with R by Michael Clark
This online guide is similar (https://m-clark.github.io/text-analysis-with-R/intro.html), and additionally covers strings and word embeddings with sample code/case studies.
This workshop summary on R-Bloggers also provides an introduction to some of these topics using a different R package for analyzing textual data in R (quanteda): https://www.r-bloggers.com/advancing-text-mining-with-r-and-quanteda/, and it additionally covers supervised classification, latent semantic analysis, and structural topic models.
Topic Modelling with BERTopic
This GitHub repository contains code and helpful demonstrations and notebooks for conducting various forms of topic modelling on text using state-of-the-art techniques (i.e., large language models): https://github.com/MaartenGr/BERTopic
