Has anyone ported the Bagplot function by Rousseeuw, Ruts, and Tukey from S to R? The S function comprises a script and a FORTRAN function. I assume porting is relatively uncomplicated, but since I have not done any porting before I would not want to invest the effort if a port is readily available.

Yes, Christian Keller did a semi-port, which I had ``finished'' long ago. When starting to experiment with it I found that it produced segfaults (in the Fortran code) semi-stochastically and I never found the time to figuring out why they happened. I can have a look and provide my "bagplot" package as source package -- but not via CRAN as long the problems mentioned remain. Can you build R package from the sources?

I have not built R package from the sources before, but there is
always a first in everything. Send me the source package and I will
give it a try.
