Thanks to Dirk Eddelbuettel, Matthias Kohl, Professor Ripley, and Bernhard Pfaff for their helpful reponses.

Here is a list of the packages they recommended:

CRAN: distr distrEx distrSim distrTEst RandVar CoCo DBI IDPmisc Matrix RMySQL ROracle RSQLite RUnit SparseM aod arules boolean coin colorspace copula deal dynamicGraph fBasics(etc) flexclust flexmix giRaph gpclib its kappalab kernalb limma lme4 matlab monoProc orientlib partsm pixmap tuneR urca

R sources: stats4

BoiC: most/all

Which of these are thought (by the community as a whole) to use S4 classes in a method/style that less experienced programmers like me should try to learn from and emulate?

Thanks,

Jeff
