[R] .Fortran and memory allocation

[Gunnar Hellmund]

Hi

I know it is not recommended to use dup=FALSE with .Fortran calls, but ...

1)
Is it possible to allocate memory for a large array of type double or
integer without initializing the array
(and how is this done)

2)
If the answer to question 1) is 'Yes':
Is it possible to pass the uninitialized array to a subroutine in a
Fortran DLL (with dup=FALSE) including the dimensions (n1, ... , n3)
in the call and then initialize the array in Fortran:

subroutine arraycall(myarray,dimensions)
integer, intent(in) :: dimensions(3)
double precision :: myarray(dimensions(1),dimensions(2),dimensions(3))

myarray=0.0

end subroutine arraycall

best
Gunnar
