Everything you get from R is already by reference (well, technically, a pointer as the P in SEXP). That is the beauty of proxy objects in Rcpp. So just simplify things, and don't interfere with R's memory management. Should be much smoother sailing. I get the feeling that are both very ambitious, yet somewhat new to Rcpp. I would simply urge patience, recommend you study a couple of existing packages and start small.
