And Fortran is still probably faster than if it used C in most cases of R's use of Fortan. http://beza1e1.tuxen.de/articles/faster_than_C.html http://beza1e1.t

And Fortran is still probably faster than if it used C in most cases of R's use of Fortan. http://beza1e1.tuxen.de/articles/faster_than_C.html http://beza1e1.tuxen.de/articles/faster_than_C.html There is just a ton of well written Fortran for number crunching and there is zero reasons to not use them. You wouldn't gain speed and you would loss the decades of stability these Fortan scripts have given the scientific community. I am guessing all of us old timers remember the pain of Fortran in the past.
