I just glanced at this for a few secs. Quick comments

-- Remove R.h (pulled in via Rcpp which is pulled in from RcppArmadillo)

-- think about using sort and QR from (Rcpp)Armadillo: because that is why we
   use Armadillo for 

-- if you can't make the error go away in one file, create two files:
   * one higher-level with RcppArmadillo calling
   * another lower-level SEXP-only set of functions with the code you
     borrowed from MASS
