Because Fortan is a complied language, as opposed to R which is an interpreter, 
Fortran is orders of magnitude faster than R
Because R is a high level programming language developed for statistical 
analyses, for many problems it is much easier, and faster, to program 
statistical analyses wtih R than Fortran.

Hello R users,
  I have a basic "computer programing" question. I am a student 
currently taking a course that uses Fortran as the main programming 
language, but the instructors are open to students using any language 
they are familiar with. I have used R previously, and am wondering if 
there is any benefit to my learning Fortran, or whether I should stick 
with R for this class. Any advice? Are there clear benefits to using 
Fortran, or things Fortran can do that R cannot?
Thank you very much for any thoughts!
Sincerely,
Paul S.
