Jan Stránský proposed the following answer:
Hi George,

> gives a really small packing

Further I answer considering that you meant packing fraction (hopefully
I will not be melted down :-).

how much is really small?

currently there is no way how to influence results of randomDensePack.
Based on its code, you can write your own function with different
parameters (friction angle of material during compaction for example).

I am not sure if I got your point, but:
1) you can use pack.regularHexa to create "oranges packing" structure, which is theoretically the densest packing of uniform particles
2) randomDensePack (with spheresInCell parameter and again uniform radius) produces packing fraction approx 0.61-0.62, which is close to 0.64, the theoretical value of packing fraction of random close packing [1]
cheers
Jan
