Many R packages still use the legacy .C()/.Fortran() function to call C/Fortran codes. When a long vector is used with these packages, integer overflow may happen. However, I have never seen any warnings of this issue in these packages. I am not sure how R could deal with this situation without introducing 64-bit integer.
