Pneumonic devices for data frames

I was going through the Swirl tutorial for my R Programming course and got to the section on data frames. This is a neat pneumonic device for remembering four initial methods to run when encountering a new data set in R. Headstrong dim sum.

Incidentally, I'm getting dim sum this weekend for the first time with some friends. I'll probably be thinking about this then, too.
