Subject: [R] Non-visible functions are asterisked

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

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
