attributes

[Steve Oncley]

During the last couple of months (at least) there has been a trickle of
messages on R-help related to attributes (other than dim/dimnames) not being 
inherited.  
Example:
	x <- 1
	class(x) <- "test"
	class(x+1) [returns NULL, not "test"]
I have not seen a response from anyone in the R-core about this issue.  
Since our group uses locally-written code (in S+) that is object-oriented, 
R is useless to us until this capability exists.

Do any of you have this on your tasks-list, or should we <attempt> to add 
attribute inheriting on our own?  Thanks...Steve Oncley (oncley@ucar.edu)

P.S. Please respond directly to me (or r-help), since I'm not on r-devel.
