[R] Organize regression output

[Bert Gunter]

Francesca:

It is hard to know what you might mean by "organize the results in an
efficient way." Some would say that a list of models already does this
for you.

The task you described is fairly simple, so I believe you would
benefit by going through an R tutorial or two to improve your R
programming skills. There are many good ones on the Web. That would
probably be a better long term strategy for you than posting basic
questions here.

Cheers,
Bert
