I had got a version with Fortran and S-plus from Dario Ringach
(@ NYU.edu) in 1994 (from what I see) and had worked on it in 2000,
made it into an R package back then.
The reason it hasn't made its way to CRAN was that the Fortran code
(which I f2c'ed to C) still has bugs (leading to segmentation
faults) that I've not yet found time to debug.
Let me have a look at it before making it available (not on
CRAN) but via FTP as a source package.
