R Programming Classes

R is a programmable environment to analyze data. It can pull data from a variety of sources and help you create visualizations. It supports command-line scripting that allows you to more easily reuse your work for other analysis and handle more complex situations. Learn to use this software tool by taking an instructor-led class from the Computer Education & Training Center at UMSL. [More on R]
