Hi, i have used S4 classes to implement a unified access to random number generators (package rstream on CRAN). I have used a construct to allow optional arguments: if(!isGeneric("rstream.sample")) setGeneric("rstream.sample", function(stream,...) standardGeneric("rstream.sample")) setMethod("rstream.sample",

...nst the development snapshot R-devel_2006-08-30.tar.gz is available. However, it is a little bit too long (239 lines) to be posted here. Of course suggestions for an alternative approach are welcome.

Hello, after some discussions with Martin Maechler and Josef Leydold (WU Wien), we have felt the need for some package that should allow for an object-orientated approach to distributions. Our small group at Bayreuth now has developed a package "distr" which tries to fill this gap, implementing distributions by means of S4--classes. A mother class &qu...

The old generator has been retained for reproducibility of older results, under the name "Buggy Kinderman-Ramage".
