NEWS, rev. 47094 now says:
o nlminb() copies names from 'start' to the parameter vector
used (for consistency with optim()).
Dear Prof. Ripley,
thank you very much for doing this.

Dear Prof. Ripley,
thank you very much for the fast response. I am very grateful for all

Dear R developers,
I tried to use nlminb instead of optim for a current problem (fitting
parameters of a differential equation model). The PORT algorithm converged
much better than any of optim's methods and the identified parameters are
plausible.
