It seems as though 'symbol.For' does not work correctly.

> library("foo")
> add(3,4)
[1] 7
> sym.add(3,5)

Error in .Fortran(symbol.For("add"), as.numeric(a), as.numeric(b), c = as.numeric(0)) :
        "Fortran" function name not in load table

The function 'add' is a R wrapper to a simple fortran 77 subroutine that adds two numbers.
In 'add' the .Fortran call looks like this:

In 'sym.add' the .Fortran call looks like this:

symbol.For works correctly if there is an underscore in the name though.

I have tested this on OSX and linux and get the same results.

I have a test package written up if anyone wants it. Email me
