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.
