Non-visible functions are asterisked
It means that the package has not exported it so normally you would not access it directly. For example, for summary.princomp you would normally pass a princomp object to the summary generic. If you did want to access summary.princomp directly, since it has not been exported, you can use the form stats:::summary.princomp as just summary.princomp won't work. Normally this would not be desirable, though. On Sat, Mar 8, 2008 at 10:48 AM, Muenchen, Robert A (Bob)

Dear R-Helpers, I suspect I'm about to ask a FAQ, but I haven't been able to find an answer in the FAQ, AItR or an R Site Search. When I look at the methods of summary (below) it says, "Non-visible functions are asterisked". I looked at the help file for summary.princomp, which did not comment on it being non-visible. I ran its help file example, which printed visible output. I did not notice how it differed from other functions, like summary.data.frame that is not marked non-invisible. What does the non-visible mean? Thanks, Bob
