Try IPSUR, Introduction to Probability and Statistics Using R. It's a free book, free in the GNU sense of the word.
It's definitely open source - on the download page you can download the LaTeX source or the lyx source used to generate this.
The official guides are pretty nice; check out http://cran.r-project.org/manuals.html . There is also a lot of contributed documentation there.
If you're an economist/econometrician then Grant Farnworth's paper on using R is indispensable and is available on CRAN at: http://cran.r-project.org/doc/contrib/Farnsworth-EconometricsInR.pdf
One resource is 'Some hints for the R beginner' at http://www.burns-stat.com/pages/Tutor/hints_R_begin.html
I have written a document that is freely available at my website and on CRAN. See the linked page:
The datasets that are used in the document are also linked from that page. Feedback is welcome and appreciated!
If you already know another programming language, these notes may help point out some of the ways R might surprise you.
I liked these lectures: Statistical Aspects of Data Mining. The lecturer is solving example problems using R.
If you are coming from a SAS or SPSS background, check out:
This is the companion site to the book, R for SAS and SPSS Users by Robert Muenchen and a free version of the book can be found here.
One more: R bloggers has many posts with tutorials materials:
There are some very good learning materials here: http://scc.stat.ucla.edu/mini-courses/materials-from-past-mini-courses/spring-2009-mini-course-materials/
Look for R Users Groups in your area. They are growing around the world.
If you don't have one then help get one started. I'm sure you will be able to find like minded interested folks.
As for helpful links the Dallas R Users Group has a nice list.
http://www.datamind.org offers interactive R tutorials, currently focused at real beginners
If you'd like a beginners tutorial to R in the context of Econometrics this may be a good starting point as well: http://www.quandl.com/learn/working-with-quandl-and-r
