kml and points

Dear All,

I have just discovered  the fantastic possibilities given with 
kmlPolygon, klmLine and kmlOverlay (package maptools) to project spatial 
objects into google earth.

Does anyone knows if a function equivalent has been written to create a 
kml file of "points" ? If not, is there a technical reason not to have 
done it or a workaround which would make such function unecessary ?
