SV: [R] Documentation of S3 and S4 classes, inheritance

I don't think you quite said what you meant ...

I thought if you wanted C to inherit from A and B you could, in S3,
just   
   class(aCObject)<- c('C', 'A', 'B')
While the ordering is arbitrary, that's usually the case with multiple
inheritance.

I assume you meant, "I thought if you wanted aCObject to inherit from A and
B,..."

In S3, classes do not inherit, only objects do. In S4, there is true class
inheritance.
