[R-sig-eco] New to R

[Wayne Richter]

I will second the recommendation that you got for Muenchen's R for SAS and SPSS Users. It's a terrific book that pretty much saved me when making the transition from SAS to R. It explains concepts clearly and shows how the SAS and R mindset's differ, something that I think is crucial in making the switch. While the 80 page early free version is good, the book is much more detailed and comprehensive. As a second book to help you make the transition, check out K. Kleinman and N.J. Horton. 2010. SAS and R: Data management, statistical analysis, and graphics. CRC Press. This book is kind of a cookbook comparison between R and SAS with lots of short examples. It complements the Muenchen book well.

For graphics, I like ggplot2 (H. Wickham. 2009. ggplot2: Elegant graphics for data analysis. Springer.

Subject: 	[R-sig-eco] New to R

OK all, I'm a research forest ecologist who worked for the US Fish & Wildlife Service and the US Geological Survey for 16 years after studying under Dr. Sharitz at the Savannah River Ecology Laboratory. Most of my work has been in bottomland hardwood forest and cypress/tupelo swamps of the Southeastern United States. My data analysis tool was SAS, and I do some programming in Visual Basic.  I now work with a very small company that has little in the way of data analysis or graphics capabilites. I therefore downloaded R and am trying to figure it out. 
 
Other than the "Introduction to R" manual and other things on the R website can you recommend a good book on R. My analysis needs are not that complex. I currently need to do an ANOVA on two tree populations to see if they are significantly different with respect to size (one area was polluted and the other is a control). I also need to do some point-quarter analysis for two separate forest populations, one in NE Texas and the other in S Mississipp).
 
Any help or suggestions would be appreciated.
