          Since I've seen no replies to your question, I will offer brief comments that will certainly not meet your needs but might get you started. I don't know what you mean by a "static member of a class". I just got 3 hits from RSiteSearch("static member of a class"), but I don't know if any one of them would help you.

          You might get more replies if you prepare another post giving a very short toy example in the form of a very few R commands to help explain what you want to do and the deficiencies in what you tried, using the posting guide "http://www.R-project.org/posting-guide.html" to help you prepare your question. The archives contain much information on classes. In particular, you might get something from Thomas Lumley's "Programmers Nitch" in the June 2004 R News. I also recommend chapters 4 and 5 in Venables and Ripley (2000) S Programming (Springer); the "polynomial" class discussed in sec. 4.3 is implemented in R package "polynom". The vision for what classes have become in recent versions of S-Plus and R is outlined in Chambers (1998) Programming with Data (Springer). However, the actual implementation in S-Plus and R were sufficiently different from that book, at least when I tried to read it a few years ago, that I found it somewhat frustrating.
