Hi Abby: Either way, thanks for your efforts with the derivative plot.
Note that John Nash is a SERIOUS EXPERT in optimization so I would just go
by what he
said earlier. Also, I don't want to speak for Duncan but I have a feeling
that he meant "inadequacy" in the CG
method rather than a bug in the R code.
