Numerical integration of a multidimensional parametric function

Hi,

For my study I need to integrate a 4-dimensional parametric function. I read the documentation concerning the numerical integration here http://root.cern.ch/drupal/content/function-integration. It shows how to integrate one-dimensional and multi-dimensional functions via Functor and Functor1D wrappers. I tried to extrapolate this method to parametric functions using the corresponding wrapper ParamFunctor. However I didn't succeed to pass this wrapper object to the IntegratorMultiDim. Is it an expected behavior? Is there any way to integrate a multidimensional parametric function using Integrator? Now I am doing Monte-Carlo integration by the ad-hoc function. The problem is that it is converging too slowly. I would prefer using MISER or VEGAS algorithm implemented in the Integrator.

Thank you for help.
