[R] Alternative to nlm()

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
