help.start(), then "Writing R extensions". You can link fortran subroutines to R by compiling them in a shared library (.so or .dll depending on your system) by the command:
R CMD SHLIB file1.f file2.f -o myfortransubroutines.so and then from R you first dyn.load("myfortransubroutines.so") and then you use the .Fortran function to call the fortran subroutines with the right arguments. Pleas read the manual to have details of implementations and variables types. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
