It's in the generic defined in a different file generics.R
We have discussed this at length, this is unfortunately a compromise we
need to take at this point. We are going to see some documentation tags spread
a bit from now on.
Long story short, CRAN checks warn about undocumented parameter; we need to
have the generic with `...` to match the base::summary signature; we shouldn't
add `...` in the actual definition since we don't use it and having it weakens
the function contract (which is discouraged).
