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.

All of those steps are accompanied by exercise sessions so that you can check if you can put the information to work.
