R help - Jan 2009 - 2D kernel density estimation in non-contiguous space

Dear all,

is there in R a function to run 2D kernel density estimation (similar to e.g.
'kde2d()') in a space that is split internally?
I think about a store floor space - basically a rectangle but divided by shelves
etc. into "alleys". The "points" are people in the store and
I would like to display where people pass more/less frequently.

Many thanks!
