S4 classes in existing packages

R-devel,

I'm interested in looking at some examples of existing R packages that
rely heavily on S4 classes to get a feel for varying styles and
package organization techniques.  Could you recommend any packages
that might serve as a good starting point?

Thanks in advance,

Jeff

our packages distr, distrEx, distrSim, distrTEst and RandVar are based
on S4 classes and methods.

As do many others, providing the variety of styles that the questioner 
asked for.  Those that are documented to do so include

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

on CRAM, stats4 in the R sources and most (all?) of BioC.
