Johann,
whether S4 is "better" than S3 is a heated subject. No-one (I think)
disputes that S4 is in some sense more flexible (for some suitable
definition of flexible), but it does incur some performance overhead
(how much is debatable) and some would argue that it also makes code
more complicate

I'm experimenting with a few model-fitting classes of my own. I'm
leaning towards using S4 for my classes, but the R functions I'd want to
override (residuals, predict, etc.) are all S3 methods.
As I understand it, I could do setGeneric("residuals"), then add S4
specializations to it. However, I
