What a surprise! I had no idea anyone was interested in this stuff or had bothered even to put it forward...

This was originally my S-PLUS front end to some work of Miller & Nguyen on finding D-optimal designs with blocking. Had I known someone was interested in porting it to R I may have found some time to work on it. As it is I will not. If the contributor (Halvorsen) does nothing more with it I think it should be just dropped. There are problems with the Fortran and it would take some work to get it going. The S code is unnecessarily complicated as well. (I did it some time ago when I was younger and more ambitious...)
