[R-wiki] rdoc pages not finding R docs?

[Tony Plate]

When I visit http://wiki.r-project.org/rwiki/doku.php?id=rdoc:base:seq , 
I see the following text:

== Rwiki file not found! ==

Be aware that due to the use of binary floating-point arithmetic, you 
may not get results that are exactly equal to what
...

The source of the page starts with "~~RDOC~~".

In fact, I see this "== Rwiki file not found==" on all of the half-dozen 
or so rdoc pages I tried visiting (with the exception of 
http://wiki.r-project.org/rwiki/doku.php?id=rdoc:base:any, which 
displayed as "~~RDOC~~"???)

Curiously, for any of these pages, when I click "Edit this page", and 
then click "Preview", I see the R documentation.
