I would like to learn about classes, methods, S3 and S4.
Which book would be the most helpful for this info, please: the green one
or the white(and blue) one?
Or is there something that would be even better, please?
Reading the source of a few packages: R2HTML (S3), zoo (S3) and its (S4) would get you up to speed quickly.
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.
