Our Verdict

The 'Text Mining, Scraping and Sentiment Analysis with R' course offers valuable insights into using Twitter data for text mining purposes. It effectively introduces various R packages and provides practical examples for implementing web scraping and sentiment analysis. However, the outdated content and insufficient detail on cleaning text data limit its overall impact. A more comprehensive approach to handling different aspects of text data would make this course even more appealing to both beginners and advanced learners.
