In short, you can't. R only has one type, so to speak -- SEXP -- and you need to decide at run-time _what type it may carry_. See eg http://gallery.rcpp.org/articles/rcpp-wrap-and-recurse/ as well as several answers on StackOverflow and in the list archives. Because R allows a <- 1L; myFunc(a) as well as other variable for a, this does not map so well. Such is life when interfacing a dynamic language.
