[R] density estimation on 2-D bounded domain

[Hans Muller]

Dear R experts,

density estimation on a 2 dimensional bounded domain
---------------------------------------------------------------------
I am currently trying to estimate the probability
density (PD) of  cancers within the breast using
the sm library with the routine

sm.density

Of course a practical PD must be limited by the curve of the breast
outline.
I don't have a clue after perusing R documentation.

!! Is there a way to calculate with R statistics
!! (with sm.density, or otherwise)
!!  such a density with an imposed boundary ??

Thanks in advance for any hint,

hans muller
