There is a mechanism for dispatching to the appropriate constructor, but
this needs extra work from you on the C++ side. I'm currently not
entirely happy about it, and this might change in the future for
something nicer.
Some information about it was posted on this thread:

Dear mailing list,
For a project I am working on speeding up a simulation in R by translating
it to C++ (using inline and Rcpp). It is done and works fine on my windows 7
64bit R, but for some reason it is not working on my supervisors latest mac
OSX (not sure of the version. should be up to date)

Hello,
Let's try to narrow this down.
Please provide a small and reproducible example.
What is the version of the compiler. This is what I have on my iMac:
$ g++ --version
i686-apple-darwin10-g++-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5666) (dot 3)

It works for unloaded packages that don't use module
Thanks, this works for me.

Hi,
Here is a small example:
library("Rcpp")
library("inline")
fun <-cxxfunction(,
'
Environment e = Environment::global_env();
NumericVector bar = e["foo"];
bar = bar + 1;
return wrap(bar);
',plugin="Rcpp")
foo <- 1:10
fun()
This function works fine on my windows netbook, but does not work

Hi Dirk,
yes, this makes sense, thanks. I originally added the CxxFlags(),
because one of the packages I'm linking to defines where to find the
Boost headers, but I see that it's not needed in all cases.
Thanks!

It's Romain's trick, really, as you can see from the thread Dirk mentioned. I
was just the first to use it in a CRAN package.
