dotCall64: An R?package providing an efficient interface to compiled C, C++, and Fortran code supporting long vectors

摘要

The R?package dotCall64 provides an enhanced version of the foreign function interface?(FFI) to call compiled C, C++, and Fortran code from the software environment?R. It allows users to integrate compiled code without using complex application programming interfaces (APIs), such as the C?API of R. Moreover, dotCall64 supports long vectors having more than231?1elements and implements a mechanism to avoid unnecessary copies of R?objects. Therefore, dotCall64 facilitates making existing C, C++, and Fortran libraries accessible for R?and is particularly useful for applications involving long vectors.
