[Rcpp-devel] How to use sourceCpp() to call a file with '.hpp'

I have found a .hpp file called fn_kron.hpp, and I have learned that sourceCpp() can be used to call c++ file to R. But when I wrote in this way, it returned the filename must be '.cpp', so how could I use sourceCpp to call this package? 


Thanks for your help. :)

You have a file ending in hpp.

sourceCpp wants a file ending in cpp.

Impasse? No, create a one-liner cpp file sourcing the hpp file. Or just rename.
