This is discussed on the same page (130) as kde2d in the book it 
supports.  The posting guide does say

     * If the function is from a package accompanying a book, e.g., the
       MASS package, consult the book before posting

so how on earth did you miss that?

There are other ways to do this: see e.g. package sm.
