I'm going to try my hand at converting some Fortran programs to R. Does
anyone know of any good articles giving hints at such tasks? I will post
a selective summary of my gleanings.
Presuming you don't mean .Fortran(), I have gone both ways. Aside from
the obvious fact that a single R vectorized command can replace either
just a loop or an entire Fortran subroutine, I don't have any deep
insights. I simply did a line-by-line translation to R, confirmed the
code still worked, then looked for simple optimizations/refactorings.
If you have a lot of code to port, and are hinting you would like an
automated tool, I think you are out of luck ;) There is a Fortran to Lisp
translator (f2cl), but I think the resulting code will not get you a lot
closer (it is aimed at compilation).
Cheers, David Duffy.
