Dr. Varadhan:

   Perfect. Package Rsolnp is exactly what I was looking for.  Thank you very 
much.

You have nonlinear constraints on the parameters.  Take a look at constrained 
optimization algorithms in packages "alabama" or "Rsolnp" that can handle 
non-linearly constrained optimization problems.
