Take a look at demo(Mel) in the quantreg package.

 have nearly computed everything but I am searching for an estimator of the
 density of the distribution at several points of the distribution. As the
 quantreg-package of Roger Koenker is also able to compute confidence
 intervalls for quantile regression (which also contain data concerning the
 estimated density) I wanted to ask wether someone could tell me if it is
 possible to extract the density of the underlying distribution by using
 the quantreg package.
 I hope my question is not to confusing, thank you very, very much in
 adavanve I appreciate every comment=)
 Cheers
