Re: [R] Aquamacs Preferences not showing, windows inaccessible, Scrolling not possible !!!

I think you'll have better luck on the aquamacs help list. To verify that it is an aquamacs problem, you can try a different version of emacs (e.g., http://vgoulet.act.ulaval.ca/en/emacs/) and see if the problem persists. Best, Ista On Sat, Jan 12, 2013 at 4:17 PM, Christian Hoffmann

Hi Nicole, One nice thing about R is that it is often easy to see the code for many functions. For summary.lm just type the name at the command prompt (no brackets) to see the function definition. There you will find ans$adj.r.squared - 1 - (1 - ans$r.squared) * ((n - df.int)/rdf)
