Hi, I'm looking for some guidance on whether to use
S4 or Reference Classes for an analysis application
I'm developing.
I'm a C++/Python developer, and like to 'think' in OOD.
I started my app with S4, thinking that was the best
set of OO features in R. However, it appears that one
needs Reference Classes to allow object methods to assign
values (other than the .Object in the initialize method)
to slots of the object.
This is typically what I prefer: creating an object, then
operating on the object (reference) calling object methods
to access/modify slots.
So I'm wondering what (dis)advantages there are in
developing with S4 vs Reference Classes.
Things of interest:
Performance (i.e. memory management)
Integration compatibility with R packages
??? other issues
Thanks!
