How is rfi-r-fortran interface for modern fortran?

RFI: R to Modern Fortran Interface This R package provides.ModernFortran (), an interface similar to.Fortran () but for Fortran 2018. The 2018 Fortran language standard expanded support for interfacing C and Fortran. One of the additions is the introduction of C descriptors, a data structure for passing arrays between C and Fortran.
Besides, how do I use the Fortran interface with subroutines?
And speaking of subroutines it is important to know that to use the .Fortran interface one must make reference to Fortran subroutines only – not Fortran functions or full on programs. So if you have some code that you want to bring in then you will need to embed that code within a subroutine definition.
Thereof, what are external subprograms and implicit interfaces in Fortran? Fortran External subprograms and implicit interfaces. Example. A subprogram is said to be external when it is not contained in the main program, nor in a module or antoher subprogram. In particular it can be defined by means of a programming language other than Fortran.
Next, why do so many people use Fortran instead of R?
Or maybe they have written some code in R that winds up being incredibly slow so they write a much faster version in Fortran and then want to call it from R. Perhaps they need to access subroutines from external Fortran libraries.
Also, what is the difference between FORTRAN 77 and Fortran 90?
The Fortran 90 version of the function subprogram operates in much the same manner as the function subprogram in Fortran 77. Note that the only substantive difference here is the ability to explicitly declare the arguments of the function itself.

What's the difference between fortran 77 and fortran 90?

Fortran 90 is a superset of Fortran 77, that is programs written in Fortran 77 may be compiled and run as Fortran 90 programs. However Fortran 90 is more than a new release of Fortran 77. The Fortran 90 standard introduces many new facilities for array type operations, new methods for specifying precision, free form, recursion, dynamic arrays etc.

Is the procedure interface explicit or implicit in fortran?

The interface can be explicit, in which case the Fortran processor has access to all characteristics of the procedure interface, or implicit, in which case the Fortran processor must make assumptions about the interface. It is desirable, to avoid errors, to have interfaces available whenever possible.
