Hello Hao, Thank you for the advice. That did the trick! Here is a relevant thread about something similar on StackOverflow (http://stackoverflow.com/questions/20572535/error-in-dyn-load-in-rcpp-package-in-mac)).

Try installing Rcpp from source.

In case it matters, I’m running Mac OS X 10.9.1. I compiled a simple NumericVector function with no problem: library(Rcpp) src <- ' #include <Rcpp.h> using namespace Rcpp; // [[Rcpp::export]] NumericVector fun1() { NumericVector a(3, 10.0); return(a); } ' sourceCpp(code = src) fun1() When I try a similar function with a NumericMatrix, I get an error. I tried to compile: src2 <- ' #include <Rcpp.h> using namespace Rcpp; // [[Rcpp::export]] NumericMatrix fun2() { NumericMatrix a(3, 2); return a; } ' sourceCpp(code = src2) And get the following error: Error in dyn.load("/var/folders/x7/cm9jq3nn6mxdn31r9sw3sbv80000gn/T//RtmpaRBweq/sourcecpp_15e0218ec23e/sourceCpp_38196.so") : unable to load shared object '/var/folders/x7/cm9jq3nn6mxdn31r9sw3sbv80000gn/T//RtmpaRBweq/sourcecpp_15e0218ec23e/sourceCpp_38196.so': dlopen(/var/folders/x7/cm9jq3nn6mxdn31r9sw3sbv80000gn/T//RtmpaRBweq/sourcecpp_15e0218ec23e/sourceCpp_38196.so, 6): Symbol not found: __ZNK4Rcpp7RObject4attrERKNSt3__112basic_stringIcNS1_11char_traitsIcEENS1_9allocatorIcEEEE Referenced from: /var/folders/x7/cm9jq3nn6mxdn31r9sw3sbv80000gn/T//RtmpaRBweq/sourcecpp_15e0218ec23e/sourceCpp_38196.so Expected in: flat namespace in /var/folders/x7/cm9jq3nn6mxdn31r9sw3sbv80000gn/T//RtmpaRBweq/sourcecpp_15e0218ec23e/sourceCpp_38196.so Thinking perhaps I messed up, I tried to compile a stripped down Gibbs sampler example from Dirk to no avail (http://gallery.rcpp.org/articles/gibbs-sampler/). src3 <- ' // load Rcpp #include <Rcpp.h> using namespace Rcpp; // shorthand // [[Rcpp::export]] NumericMatrix RcppGibbs(int n, int thn) { int i,j; NumericMatrix mat(n, 2); return mat; // Return to R } ' sourceCpp(code = src3) What is going on? If I am missing something very simple, please forgive me. I’ve been beating my head against the wall for over an hour now looking at examples, trying to create the simplest tests possible, to no avail.
