I've been finding that the "loose ends" in many of these older codes cause more trouble
than it is worth in their use. When I encounter them, I've attempted to re-program the
algorithm in R. A lot of the Fortran code is because of the software structure the author
used and nothing to do with the job to be done.

If you can prepare an R function for this, you'd be doing the R community a favour.  You
may also find that a judicious combination of optimize() and grid search gets the task
done satisfactorily.
