After re-re-re-re-reading the documentation for optim, I think it can be forced to look for either a minimum (default) or for a maximum if need be through the control argument or, more simply , the objective function should be handled for a minimum by putting a minus sign on the return of Obj.F12...
... but even so the estimates are still somewhat off. :-D

I could be wrong, but...

Best regards,

R's base package has 274 reserved words and operators, along with 1761 functions. I can use 18 of them (about 14 of them properly). I believe this makes me the Donald Trump of programming.
