Greetings, 
 
 I am using the nlm function in a minimization exercise but have
consistently received the code: "last global step failed to locate a point
lower than 'estimate'...." 
 
So it seems that this function is only finding a local minimum, not
necessarily a global minimum. 
 
Does anyone have a suggestion or recommendation for an alternative package
or function within R that will perform this minimization task more globally?
 
Thank you, 
Marion Wittmann
