[R] calling a DLL/shared lib from R directly?

[Jeff D. Hamann]

Is it possible to call a basic function/subroutine in a DLL/shared lib from
within R without having to build an R package?

 I have a function like:

 void __stdcall testfunc2(
   unsigned long a,
   double b,
   unsigned long c  )
 {
   return a * b * c;
 }

 or=20

  subroutine fortran_2002_bh_age (sp,site,total_age,bh_age)
  integer*2 sp
  real*4 site=20
  real*4 total_age
  integer*2 bh_age

  real*4 x

  bh_age =3D some_value

  end subroutine

 I have been able to make it happen from the "writing R extensions" docs. =
 It pretty important that this library be R independent.=20

 I only get the digest version, so if you answer, could you send a copy =
 to my email address please?

 Thanks,
 Jeff.
