Nearest neighbour distances as used by Ghat()
Description
Calculate nearest neighbour distances as used by Ghat().
Usage
nndistG(pts)
Arguments
pts
A points data set
Value
Returns a list with components $dists and $neighs.
$dists[i] is the distance
to the nearest neighbour of point i in pts, and $neighs[i]
is the index
of the neighbour of point i.
