nearest neighbors

Is there an implementation of a reasonable k-nearest neighbor finder
already in one of the packages?

knn in VR/class: I'll leave you to pass judgement on `reasonable', but it
is widely used.  It may not be the problem you had in mind.

Hi,
I think splancs might have one. Otherwise I know Roger Bivand has a
preliminary port of ANN on his ftp site that i have compiled and run. ANN
is David Mounts approximate nearest neigbor package, really fat with
modified kd trees.
