I don't think external pointers can be read from R sources like normal vectors, or am I wrong? Using external pointers would imply either proxy calls for every action you need to perform or deep copies (like I'm doing now). > I wouldn't try to trick the memory manager into thinking that it > allocated these things; that will likely just lead to problems. I'm not afraid of patching R sources somehow, if that's the only solution, but it's one that I would like to avoid. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
