returning information from functions via attributes rather than return list
...not an lm anymore. I either need to write
custom methods for every function or remember to extract the object
from the list before sending to the generic function.
I *guessed* it would work to write the new information as object
attributes, and it seems to work. There is a generic function
"meanCenter" and a method "meanCenter.default". At the end of
meanCenter.default, here's my use (or abuse) of attributes.

to experiment with the benefits (or lack thereof) that flow from centering.
