R Tutorial

As part of Dr. Weigle's CS 796/896 Visual Analytics Seminar I will offer a tutorial on the statistical computing software R. I will give an hands-on introduction into data input/output, simple data manipulation, and (of course) plotting. If you for example always wondered how to fill data vectors, import data from MySQL databases, compute the mean and standard deviation, execute logic, ranking and sorting operations, compute correlations and linear regressions, use loops and write functions as well as create scatter-, bar-, box- and other plots and all that in R, you will enjoy this tutorial. The tutorial is targeted towards course participants which have a natural interest in data visualization but it also has merit for other MS and Ph.D. students doing research and consequently dealing with and plotting data.

While this introduction naturally can not cover all aspects of R and does not claim to be exhaustive, it will help students getting started with the software and the material will serve as an "almanac" in the future to generate pretty graphs such as the one shown here.
CS796/896 is not open to the public but the material covered in the tutorial can be obtained here.
If you have any questions, comments or would like to contribute to augment the materials do not hesitate to contact me.
