perhaps that what it maps to in R, I haven't checked closely.
though I'd think it'd be better to be consistent with Scala so they could
be more easily discoverable.
also I think we should change the `@family` name into full text instead of
the short form some_funcs - that shows up in the generated doc. I didn't get
around making all those changes but might make sense in the 2.3 release.
