Tim Clapham provides a quick tip which shows how to essentially create the Cinema 4D Atom Array with Cloner Objects, in a method that will give you more control over the spheres in the Array.

the trick here is to use the Edge Scale parameter in the Cloner Object, This allows you to scale the clones to fit the length of the edge

Tim notes that the first Cloner adds a Sphere to each vertex of the object that you are cloning onto, and the second Cloner Object adds a cylinder to each edge of the object. Check out the quick tip for Recreating the Atom Array With Cloner Objects in Cinema 4D here.
