This course will teach you anything you need to know about how to handle social media data in R. We will use Twitter data as our example dataset.
During this course we will take a walk through the whole text analysis process of Twitter data.
At first you will learn which packages are available for social media analysis.
You will learn how to scrape social media (Twitter) data and get it into your R session.
After that we will filter, clean and structure our text corpus.
The next step is the visualization of the text data via wordclouds and dendrograms.
And in the last section we will do a whole sentiment analysis by using a common word lexicon.
All of those steps are accompanied by exercise sessions so that you can check if you can put the information to work.
According to the teaching principles of R Tutorials every section is enforced with exercises for a better learning experience. You can download the code pdf of every section to try the presented code on your own.
If you are not yet on an advanced level in R programming, we would highly recommend our R Level 1 course. The Level 1 course covers all the basic coding strategies that are essential for your day to day programming. R features like functions and apply are covered in the Level 1 course and are also needed for this course.
