[R-sig-Geo] Nearest neighbor for two spatial datasets

I am looking for a fast implementation for finding, for each object in 
dataset A, the closest object of dataset B. A naive approach using 
gDistance et al. considers each pair AxB, but this can be improved by 
using a spatial index in B.

Is there such an implementation for R?
