R help - Mar 2009 - Fortran-90 and R

I have some code in Fortran-90 that outperforms my R implementation of the same
algorithm (in terms of speed).
I wonder whether it is possible to interface R with Fortran-90. that is would
like to call a Fortran routine from my R
script, passing to the Fortran routine some real numbers array, some scalar real
numbers, and an integer number .
I have no idea how to do that because Fortran is a compiled language whereas R s
an interpreted language ..
therefore I do not know whetehr it makes any sense to build a make file for the
linker ... Is the linker necessary ?

Thank you very much.
Maura

You need to read this:
