Optimization is not something "R" does... this is something implemented by 
specific functions that may be in the base install or in add-on packages, 
but you have not indicated how you are currently approaching your problem.

If you are using the optim() function, then I refer you to the fine 
manual under the control argument. Type


at the R command line.

For advice on how to communicate clearly on the topic of R, I recommend 
that you also read 
before posting again.
