%description
An R wrapper for 'libnabo', an exact or approximate k nearest neighbour
library which is optimised for low dimensional spaces (e.g. 3D). 'libnabo'
has speed and space advantages over the 'ANN' library wrapped by package
'RANN'. 'nabor' includes a knn function that is designed as a drop-in
replacement for 'RANN' function nn2. In addition, objects which include
the k-d tree search structure can be returned to speed up repeated queries
of the same set of target points.
