Getting to know the "apply"s in R is extremely handy for using the language efficiently and effectively. Unfortunately, the help files tend to be rather information-dense and are fairly overwhelming for newcomers. A recent blog post by Neil Saunders provides a thorough overview and tutorial of the apply family, illustrated by simple and reproducible examples. I suspect I will refer to it frequently from here on in.
