Robert Caulk proposed the following answer:
Hello,

Actually, these are not parameters of randomDensPack. randomDensePack()
employs a function called TriaxialTest()[1], which generates a
triaxially compacted packing given various parameters
(sigmaIsoCompaction being one of them). Just to be clear, you cannot
control sigmaIsoCompaction through randomDensePack(). randomDensePack()
is a module that promises to return a stable and dense packing for your
geometry.

assumedFinalDensity is simply used to estimate the number of spheres it
will need to fill the requested volume. The user does not have control
over that value.

TriaxialTest() does not create a packing with a user-specified porosity.

Cheers,

Robert
