(:title R Lecture and Notes:)

On September 26, 2013, I presented a brief introduction to [[http://www.r-project.org/|R]] for Dr. Nelson's [[http://www.cs.odu.edu/~mln/teaching/cs595-f13/ | CS 595 Introduction to Web Science]] class.  The slides and source code used follow:

* [[(Attach:)cs595f13-R.pdf|Slides]] (PDF).

* [[(Attach:)load.R|load.R]]: My typed data table loader.

* [[(Attach:)create-spread-scatter-charts.R|R Source Code]] to produce the spread chart (below).  Again, this code produces many other charts and tables.  The <em>scatter.plot</em> function performs the bulk of the work.  The data for [[http://www.rpgdreamers.com]] is [[(Attach:)extract-bracket-multi.txt | here]].
