>From the manual:

Unit groups are created as sub-groups within the units member of the
layer. The z value of the layer's geometry specification indicates how
many groups to create, and each of them has n_units units arranged in
the geom.x, geom.y geometry as specified in the layer. However, once
created, the unit groups can be individually re-sized, and they have
their own n_units, geom, and pos variables. To have a unit group
always use the settings on the layer, the n_units should be set to 0. 

Note that the input pattern in the environment does not (currently)
have support for sub-groups of unit values, so you just have to
organize it as one big layer.  set the x geom to be the x geom of the
layer, and the y geom to be y * z.
