A preliminary version of an R package for classes and methods is available from the omegahat web site: http://www.omegahat.org/RSMethods/index.html Documentation and source for download are available from this page. The goal is to support an API that would provide compatible facilities for defining classes and methods in R and S-Plus. For the moment, the "API" is roughly taken from "Programming with Data", particularly section 1.6. A revised version of that section is available, from the web page above, modified a bit for R use. This is a preliminary version; comments and suggestions on any aspect would be much appreciated, before going more "public" with it. The current version is all written in the S language, for flexibility. Key portions (method dispatch at the least) will be implemented in C later on for efficiency. Regards, John Chambers
