If you are new to R, and want to get an introduction to the R language, in the classic “learning by doing way”, Code school and O’Reilly have put together the Try R interactive tutorial.
This tutorial is a painless introduction to the R programming language. During the course you'll become familiar with using vectors, matrices, factors, and data frames to manipulate data into powerful visualizations.
For new comers, it might sounds daunting, but if you have few minutes why not give it a try?
Here is what the course outline is and you’ll earn cool badges like the one on the right as you make progress!
Level 1 - R Syntax
A gentle introduction to R expressions, variables, and functions
Level 2 - Vectors
Grouping values into vectors, then doing arithmetic and graphs with them
Level 3 - Matrices
Creating and graphing two-dimensional data sets
Level 4 - Summary Statistics
Calculating and plotting some basic statistics: mean, median, and standard deviation
Level 5 - Factors
Creating and plotting categorized data
Level 6 - Data Frames
Organizing values into data frames, loading frames from files and merging them
Level 7 - Working With Real-World Data
Testing for correlation between data sets, linear models
Level 8 - Installing Additional Packages
Extending R with additional libraries

Would love to see that logo on a t-shirt or hat!
In the meantime, any objections if I use a copy of the logo in email, etc. (not commercially) to encourage use of R at my company?

Carl, you'd need to contact the people behind Try R and ask permission to use that logo. You can probably contact them via http://www.codeschool.com/pages/about

The interactive tutorial doesn't seem to work for me.
