Hi Chistian,
With sourceCpp, you can actually specify an exported function name
explicitly in the export declaration. For example:
// [[Rcpp::export("fun.class")]]
So this will work for sourceCpp but alas isn't currently possible for
cppFunction. One way around this for cppFunction would be to pass env
= NULL to cppFunction which will result in the function being returned
rather than added to the calling environment. You could then wrap the
returned function in an appropriately named S3 function.
