Hello,
This is related to this change:
2013-01-15 Dirk Eddelbuettel <e...@debian.org>
* src/api.cpp (Rcpp): Commented-out coerce_to_string() for real and
complex arguments as R-devel (as of today) dislikes use of non-API
functions Rf_EncodeComplex’, ‘Rf_EncodeReal’, ‘Rf_formatComplex’
So maybe Dirk has a plan to fix it.

Hi guys,
When I attempt to 'sourceCpp' the following code, the R session
crashes:
#include <Rcpp.h>
using namespace Rcpp;
// [[Rcpp::export]]
IntegerVector counts(NumericVector x) {
return table(x);
}
The same code worked in Rcpp 0.10.2.
A hint to the error comes if I try to compile a package with that
source code in a .cpp file: I get the error, when attempting to load
the package:
dlopen(/Library/Frameworks/R.framework/Versions/2.15/Resources/library/anRpackage/libs/x86_64/anRpackage.so,
6): Symbol not found:
__ZN4Rcpp8internal16coerce_to_stringILi14EEEPKcNS_6traits12storage_typeIXT_EE4typeE
Referenced from:
/Library/Frameworks/R.framework/Versions/2.15/Resources/library/anRpackage/libs/x86_64/anRpackage.so
Expected in: flat namespace
in
/Library/Frameworks/R.framework/Versions/2.15/Resources/library/anRpackage/libs/x86_64/anRpackage.so
This is with R 2.15.3 on Mac OSX 10.8.3.
-----
In addition, if I attempt to compile Rcpp from source (with gcc 4.8)
I
get the following warnings:
install.packages("Rcpp", type="source",
INSTALL_opts="--no-multiarch")

although the package does install successfully. Not sure if it's
related or not.
