	  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.
