R help - Feb 2005 - how to calculate density of multinormal distribution at a given point?

Dear all,
I am trying to estimate the point density of a posterior distribution 
(this to estimate a bayesian factor in aphylogenetic analysis ).  The 
problem that I would like to look at several variable at the same 
time. From a quick look several of the paramaters that interest me 
are correlated  and I need to estimate the density altogether.
  I would be very interest to know a kernel density (like the function 
"density") for multinomial distribution, but I would be equally happy 
if somebody could tell how to estimate point density with a 
multinormal distribution with known mean and covariance matrix
thanks
