R packages are the best way to distribute R code and documentation, and, despite the impression that the official manual (Writing R Extensions) might give, they are really are rather simple to create.
Even for code that you don't plan to distribute, you'll find it is easier to keep track of your own personal R functions if they are in a package. And it's good to write documentation, even if it's just for your future self.
Hadley Wickham is writing a book about the basics of R packages. You might just jump straight there. But there is value in having a diversity of resources, so I thought I'd go ahead and write my own minimal tutorial.
