A pirate's favorite programming language... and mine too?

I'm a daily MATLAB user for data analysis, and fairly fluent with most toolboxes, including Parallel Computing. I know I need to learn something new, though.* (MATLAB is great for prototyping but unwieldy for real data-crunching.) I'm taking a class (Bayesian stat methods) starting in January based around R. What's the best resource to get started with R for someone like me? [more inside]

R Statistical Computing for Semi-Dummies?

StatFilter: Would anybody be able to recommend a good introduction to the statistical computing language "R" that a reasonably quantitatively-adept psychologist might be able to work through on his own? Something like a step-by-step book or textbook with exercises would be great to help me become more fluent in R. (My colleagues at work who use R are primarily computer scientists who either first learned MatLab or are brilliant autodidacts when it comes to learning different scripting languages, and thus don't have any suggestions; Googling has mostly proferred a somewhat obscurely structured guide from the R authors and lots of invocations to just learn on my own, somehow...). I've become familiar with how to do many individually useful tasks in data structuring and analysis, but I feel a bit like a very high-functioning tourist who has learned a lot of phrases to get around but who would be lost and mugged in an alleyway if I strayed off the beaten path.

Statistical analysis package for OS X needed.

SPSS is fine but produces offensively ugly figures. R has nice, clean output but is otherwise inscrutable. Statistica is, alas, Windows-only. Mathematica isn't really it, either. What statistics package should I use for OS X? [more inside]
