Rcpp(Armadillo) behaves like any other R package.  

You can redistribute it in source (as we usually do), or in binary (as is
common for Windows as AFAIK also for OS X).  You could also create binaries
for, say, Linux which may work on identical machines (but doing so is
"unusual").

The safest bet is most often installation from source.

Start with "R CMD INSTALL --help" and the "Writing R Extensions" manual. If
you have follow-up questions, try the r-devel list or other venues as there
really is not anything particular about Rcpp here (apart from how packages
using Rcpp need to link to Rcpp, but that is documented too in the
Rcpp-package vignette and other places).
