I think that many search facilities are helpful here:

  1. help.search() searches all libraries on your computer by default.
  2. RSiteSearch() has an option of searching all functions in all existing packages, in case you don't have a package and turn out to need it: RSiteSearch([topic],restrict="functions")

I doubt that the sort of manual you describe is possible given the very rapid growth of CRAN, and it would be really inadequate if it did not include those packages. Many of them are designed for people in particular fields and turn out to be extremely useful.
