[R] mixed-integer optimisation

Does anybody know of a R package to solve mixed-integer quadratic optimisations with constraints?

Alternatively is anybody working with an R interface to ILOG CPLEX which seems to be the 'best' commercial product in this area?

Finally, is there any relationship between the R-project and AMPL - a modelling language for mathematical programming <www.ampl.com> - which also originated in Bell Labs?
