For an example, see the R loess.smooth function which uses k-d trees.
Try ?loess.smooth for info and just type
like that exactly to see source. It calls a C function that calls a FORTRAN
function to do the real work, presumably for efficiency reasons. You can
view those by looking at:

Unfortunately the above is in FORTRAN whereas you seem to be looking for a
pure R solution but hopefully that will get you started.
