nearest neighbor 3d point pattern

Carsten Neumann 
Dear list members,

after searching R mailing lists, I wonder if there is a R function that
can find the nearest neighbor/or just euclidean distance of points in
one 3D coordinate system to points in another 3D coordinate system. The
function nncross {spatstat} can only deal with 2D point pattern. Any
idea or experiences with such procedures?

######################Test Data############################
point1<-array(c(seq(0,1,0.1),seq(0,1,0.1),seq(0,1,0.1)),dim=c(11,11,11))
point2<-array(c(0.8,0.3,0.5),dim=c(1,1,1))
#########################################################
question: where is point2 in point1?


Thanks in advance

Carsten
