The problem class of 'mixed complementary problems' is quite big and 
encompasses difficult optimization problems such as nonlinear systems of 
equations, nonlinear optimization problems, or optimization with equality 
constraints, among others.

There is no solver or package in R that will solve 'mixed complementary 
problems' in general. Perhaps your problem can be cast into a more specialized 
form that is accessible to one of the available solvers. Otherwise, GAMS has 
its own module for solving MCP problems.
