Help about nlminb function

How are we supposed to help you if we have no idea how you are using it? 
Did you read the PORT documentation? Did you look at the control 
parameters outlined in the function help page? Often times for me a return 
of the initial conditions is an issue with either inappropriate tolerance 
or having variables on very different scales.

Since you did not follow the posting guide (important part *'d below), my 
only suggestion is to ?nlminb

Hi Everyone,

  Can anyone help me resolve a problem that i'm having with nlminb. The
problem is that it stops after just one iteration and returns the same
values as "start" ones.


Thank you very much for your help.


Sincerely.
