Hi Last year, there was a thread discussing S4 classes in existing packages.
I'm thinking of converting one of my packages from S3 to S4 and am having difficulty getting started. I have "Programming with data" right here, and "S4 classes in 15 pages, more or less". I have also been looking at the packages that are listed below... ...but what I really really want is a "hello, world!" package that implements the track example in the Green Book and illustrates best practice for S4 methods. Has anyone coded up such a thing?
