Link to documentation of methods

[mgirlich]

DBI has this nice feature of listing the installed methods and linking their help page (see the attached image). It would be great for other backends (e.g. dbplyr and dtplyr) if dplyr could do the same. This would help (at least a little) in issues such as https://github.com/tidyverse/dbplyr/issues/996.

It already does. Is there a generic we're missing?

[hadley]

Oh copy_to(), I guess.

[mgirlich]

I found a couple that are missing:

• copy_to()
• db_*(), e.g. db_explain()
• sql_*() e.g. sql_join()
• rows_*()

[hadley]

I'll leave db_* and sql_ as is since they're not user facing
