r-cran-dotcall64 - 1.1-1-1 main

Provides .C64(), which is an enhanced version of .C() and .Fortran() from the
foreign function interface. .C64() supports long vectors, arguments of type
64-bit integer, and provides a mechanism to avoid unnecessary copies of
read-only and write-only arguments. This makes it a convenient and fast
interface to C/C++ and Fortran code.
