I just did some of this learning myself. Here are a couple of links
that I found useful:
http://www.stat.auckland.ac.nz/S-Workshop/Gentleman/S4Objects.pdf
http://eeyore.ucdavis.edu/stat250/OOP.html
I found the first particularly easy reading and it got me going quickly
with S4 methods, which it seems to me are the way to go in most cases.
