As you never got a reproducible example, let me jump in to this old
thread as the error discussed, viz.
   class Rcpp::InternalFunction_Impl<Rcpp::PreserveStorage>' has no
member named 'update'
comes up with both the version of Rcpp on CRAN as well as the version
on github when running
this reproducible example:

code <- '
#include <Rcpp.h>
using namespace Rcpp ;

void callback(){
    Rprintf( "hello from calback\n" ) ;
}

// [[Rcpp::export]]
InternalFunction get_callback(){
    return InternalFunction(&callback) ;
}
'
library(Rcpp)
sourceCpp(code = code, verbose = TRUE)

This example is from Romain who posted it on SO here some time back
except I added a & before callback in the last line.

I am on Windows 8.1 and am using  "R version 3.1.0 Patched (2014-05-08 r65552)"

(Note that the version of Rcpp on github fails when installing during
building the vignette so I built it without vignettes; however, the
problem occurs on the CRAN version too as mentioned.)
