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 On Mon, Jul 8, 2013 at 4:57 AM, Hermann Norpois <hnorp...@gmail.com> wrote: > Hello, > > how can I retrieve electively data from a summary file, for instance I > would like to get the Pr of Coefficients > Thanks >> summary (plasma_glm_1) > > Call: > glm(formula = ESR ~ fibrinogen, family = binomial(), data = plasma) > > Deviance Residuals: > Min 1Q Median 3Q Max > -0.9298 -0.5399 -0.4382 -0.3356 2.4794 > > Coefficients: > Estimate Std.
