Workshop on #R and Twitter On 1st Dec. 2015 I will give a workshop at the GESIS Computational Social Science Winter Symposium 2015 . Using R to harvest the Twitter STREAM API R is a free software programming language and software environment for statistical computing and graphics. Because R is a programming language its usage is not limited to the field of statistics. There are already many R-packages to cover the whole spectrum of social media analysis from web scraping to text mining. This is a hands-on-tutorial to analyze data from twitter in R. In four steps, the tutorial demonstrates how to get the desired data, how to “clean” it, how to analyze it, and how to visualize the results. By following these steps the participants will gain knowledge about the general structure of R, its basic grammar, some relevant packages for social media analyses, the twitter streaming API, and about some basic programming concepts. The tutorial addresses readers with little previous knowledge
