[R] quadratic problem with quadratic constraint

[David Khabie-Zeitoune]

Sure -- just use a Lagrangian multiplier to bring the constraint into the objective function and then use a QP routine like quadprog (in the quadprog library). You will need to run an *outer* optimisation to find the value of the Langrangian multiplier.
