Is it correct that there is no way of avoiding deep copying of data structures? Or asked from a different perspective, is it true that there are no pointers? :) (not that I am a fan of pointer, they just let me decide when to do deep copy on my own when the memory manager doesnt do it for me :) ) I was considering writing code in R that would need the internal representation of complex graph

...e above example? Second, R core integration (this bothers me much more): > X$methods(m = function(t) a*t) > environment(x$m) <environment: 059bf6a4> environment(..) does not return the refObject but the basic type. I assume that it is the same with other core functionality. Usage of refObjects as parent.env is also probably precluded in the similar way (don't have a patched R, so can not test yet). Would it be possible, some day, to use refObjects as parent.env or function's environment without "loosing the class"? Parenthetically, the attributes of an object (includ...

I am using environments to avoid making copies (by keeping references). But it seems like there is a hidden copy going on somewhere - for example in the code fragment below, I am creating a reference to "y" (of size 500MB) and storing the reference in object "data". But when I save "data" and then restore it in another R session, gc() claims it is using twice the

Good afternoon, earlier today I wrote a mail to the user mailing list about current status of the current development. As pointed out by Mr. Rücker, it seems to be good to also write to this list with a bit more technical details. Please note that this mail represents current master branch ("2.5.x"). We do recommend to use current stable branch ("2.4.x") for production.
