You have a couple of major points of confusion that I'll address briefly and then direct you to appropriate reference material.
I) R is not compiled. It is an interpreted language. 2) R and Fortran are not equivalent. Something that is good code in one is not likely to be good code, or even valid code, in the other. 3) source() only tells R to execute a sequence of commands sequentially (with some printing options turned off) -- no more, no less. It's almost the same as running those commands directly at the interpreter. If you want to learn to use compiled routines within an R context, please look at http://cran.r-project.org/doc/manuals/R-exts.html, particularly chapter 5, and ? .Fortran Any further help will require you give, at an absolute minimum, OS and R version information and will likely require information about your fortran compiler (probably best to use R's provided ones -- either at http://cran.r-project.org/ (click through for your OS)) and which fortran you are using (they aren't all equally supported).
