Dear Rcpp developers:

Thanks for developing and maintaining the Rcpp package.
I wrote a function in Rcpp. It is available throughout the package and
works as expected; however, it is not available for praLapply workers. A
temporary fix is just using Rcpp::cppFunction inside the function that
parLapply workers call and copy the entire function over there. However,
this does not seem right for bigger and more complicated functions.
I would be grateful if you could let me know whether there is a better
long-term solution. Here is the package and three functions that you might
want to take a look at.

Original cpp function:

Wrapper function that calls this function + temporal fix:

The function that uses parLapply (please see line 63-89) to run the c++

Best regards,
