R-help archives --- are they up-to-date?

The searchable archives may lag, and apparently do. The main list
archive is here:

https://stat.ethz.ch/pipermail/r-help/

and is complete. That's the one to check if you wish to know whether
something made it to the list.

If you go to the r-help listinfo link in the mailing list footer, you
are directed to the link I posted, and the searchable archive is also
mentioned.
