My Favorite R References

Here are some references I’ve found particularly useful when developing or debugging R code.  When trying something new, I like to have a user’s guide open at my left elbow, a language reference guide open at my right elbow, and a steaming cup  above the keyboard.  (With R, that cup usually needs to be a soothing glass of Riesling instead of the usual jolt of coffee.)  When debugging, I like to have a debugger reference on the left, and a large unloaded revolver at my right.  (The bugs find the revolver intimidating, and I find that angry clicking sound more rewarding than admitting my programming errors.)

Framework

To effectively learn a new programming language, I like having a well-organized written framework that guides my perspective on the structure and use of that language.  Here are a couple of on-line documents that provide that kind of framework.

R User’s Guides

These focus on techniques for using specific methods.  They are generally stronger than beginner’s introductions.
