Agreed, especially for library and the like where . But from a user perspective most of the advantage of ?mean and ??mean over help("mean") is the reduction in typing - especially the utility of things like only typing the ? in
after "Error in rnorm(q = 23) : unused argument(s) (q = 23)". That is so useful that I'd say it's worth reinforcing by using ? without quotes where possible.
