length.VoxelSpace
AMAPVox allows to discard empty voxels in the voxel file. In such case
length.VoxelSpace
will return the expected number of voxels as if
none were missing. As a consequence the number of voxels stored in the
VoxelSpace
object may be inferior to the returned
value, namely nrow(x) <= length(x)
