a simple option is of the form
   fit$eval[fit$estimate==max(fit$estimate)]
assuming that fit$eval is the vector of evaluation points,
and fit$estimate the corrisponding density estimates (this is
the sort of output produced by sm.density)

Here I have assumed there is single mode and we are in the scalar
case, for simplicity. Some variant required in the more general case.
