[R] Fortran (77) in R

[Ko-Kang Kevin Wang]

Hi,

I'm learning Fortran and trying to load a Fortran subroutine into R.

I've done:
   R SHLIB Fibonacci.f
and it compiled fine.

Then I went into R and done:
> dyn.load("Fibonacci.so")
> Fib <- function(n) {
+     .Fortran("Fibonacci",
+              as.integer(n))[[1]]
+ }
> Fib(5) 
Error in .Fortran("Fibonacci", as.integer(n)) : 
        C/Fortran function name not in load table

The dyn.load() worked fine, or so it seems.  I then tried writing a
function that calls my Fortran subroutine.  However the error message was
displayed, which I have no idea what it mean ;-(

Any help will be greatly appreciated!


Cheers,

Kevin
