Good afternoon,

I am a Biology researcher working on Functional Morphology and Behaviour 
in mammals. Nowadays, I have a series of morphological data that I would 
like to test against different models for which I would need to optimize 
them -namely, "randomly manipulating" all models parameters in order to 
find the model that fit best upon my data.

I've been told that the function "optim" is THE function for me, but 
I've been having problems to program it and set all constraints.

Is there anything you could help me (guide me) with? I've asked already 
several "experts" in the internet but noone gave me a real solution.

Thanks a lot, have a nice day,
