Dr. Paul Murrell will offer his "Graphics in R" course online at statistics.com May 5 ? June 2. This course teaches you how to produce publication-quality statistical plots of data using R (a freely available open- source statistical language and environment). It will cover plots such as scatterplots, bar plots, histograms, boxplots and Trellis plots. It will review the underlying model used to produce plots in R so that you can extensively customize these plots. Finally, the course will introduce the grid graphics system and look at producing unique plots from the ground up using basic components. Dr. Murrell, the author of "R Graphics," has been a member of the core development team for R since 1999, with a focus on the graphics system in R. He is the Editor-in-Chief of "R News," the newsletter of the R project, and an Associate Editor for "Computational Statistics." He is also Chair of the American Statistical Association's Statistical Graphics Section, and a Senior Lecturer in the Department of Statistics at the University of Auckland, New Zealand. The course lasts four weeks and consists of a series of four weekly lessons (directed readings and/or notes, plus exercises). Direct interaction (Q&A) with the instructor throughout the four week period takes place via a private discussion board. Expect to spend about 5-15 hours per week; there are no set hours when you must be online.
