[R] retrieve data from summary output

[Bert Gunter]

1. It's a summary **object**, not a file.

2. ?summary.glm

3. Read "An Introduction to R" and ?"[" to learn how to work with
lists and extraction functions, which are essential.

4. Also
methods(print)
stats:::print.summary.glm  ## for code of how object is printed



Cheers,
Bert
