Learn R, a free software environment for statistical computing and graphics

US Geological Survey

The webinar course is designed for natural resource managers and is open to all who are interested without charge. R (the open-source/free version of S) provides a comprehensive environment for statistical analysis and graphics that is unrivaled in the availability of new, cutting-edge applications. It runs under most operating systems. Audio of the presentations is available either using your computer speakers and optional microphone or headset or by calling a phone bridge long distance. Live video of the presenter's computer screen is available over the web. You can also share your computer's screen with other participants when asking a question or making a point. An audio and video recording of the presentations and discussion will be available on our FTP site after the presentations. There are no specific prerequisites but some knowledge of statistics would be helpful. A basic knowledge of computers and the internet will be assumed.

This course (http://www.fort.usgs.gov/brdscience/learnR.htm) will start June 7, 2011 and will meet for about an hour on Tuesdays and Thursdays. The times will be: Hawaii 8:00 AM, Alaska 10:00 AM, Pacific 11:00 AM, Mountain 12:00 Noon, Central 1:00 PM, Eastern 2:00 PM, UTC 18:00. The course will continue until we finish the outline. We will use Michael J. Crawley, 2007, The R Book, Wiley, 942 pages, list price $110.00, but available at discount for $81 (We do not recommend book sellers. compare prices using a sites such as BizRate, or NexTag, or PriceGrabber.) It is a relatively comprehensive reference on R, although no text can cover the over 2,900 packages available in R. The course will cover the R procedures, not the statistics, which can be learned from the text book. The course will primarily use the command approach, using the Tinn_R editor.
