[R] mutable objects

[Vadim Ogranovich]

Hi,

I need "mutable" objects that I can safely modify in my C code. All call
interfaces, e.g. .C, .Call, etc., require you to not modify the "in" args.
The description of the OOP package in R-news from Sep 2001 alludes to a
possiblity of such objects, but the package itself is no longer on Omegahat
and I am not sure I need the full machinery.

Thanks, Vadim


P.S. I wonder what is the relationship between the "methods" package and the
OOP package described in R-news from Sep 2001.
