Connection to memory (R)

Question

I have to repeatedly serialize (big) R objects. To avoid repeated garbage collecting of the resulting raw vectors (after profiling, it turns out that half of my script running time is spent in gc!) I’d like to ask R to directly write in a memory buffer -- always the same, as after each serialization I’d call a C function with .C that would work directly on this memory buffer; it is the result of this C function that interests me.

Is that possible? How unreasonable is it?

Thanks in advance.

I might not have understood your problem, but why don't you directly use your R object in c++ code using Rcpp. There will be no copy and you don't not need any serialization.
