[Rd] S4 Objects [Sec=Unclassified]

I am new to R programming but have dived into a medium sized modelling software development project.

Having come from a Java OO background I have a couple of questions about S4 objects.

Is there a way to make S4 slots (and methods) private and hence force the use of accessor methods?

Is there a straight-forward way to implement pass-by-reference for method parameters?

I am currently returning and overwritting updated objects which is clunky and costly and would like a more efficient way of doing this.

Can anyone point me to some useful texts on S4 programming apart from the following:

Chambers - Software for Data Analysis: Programming with R

Venables - S Programming

Thanks heaps

Troy
