Subject: retrieve data from summary output
In-Reply-To: <CAKyZeBtmpcBjvbm3M+RQF6HZcD_gWJBE+rw11=ahQgTDgoctkw@mail.gmail.com>
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
