[R] Alternative mail archives?

[Mark Van De Vyver]

Hi, 
The searchable mail archive at http://maths.newcastle.edu.au/~rking/R/ is
very useful.  Unfortunately it seems that many of the emails are not
available, many show up in the search results but then return a "file not
found" when following the link.
Is anyone else experiencing this, and is there an alternative mail archive
with a search facility?
TIA
Mark
