[R] R Function Guide

I was wondering if there was anything for R like the function guide 
provided by insightful for S-Plus at the url below:


What makes if particularly appealing is the organization of 
functions by class.

If there is not something like this for R, I think it would be a great 
addition to the R documentation.  It would provide an easy way to 
identify an available function for a particular category of analysis 
and thus facilitate viewing the help pages for the appropriate 
function or functions--particularly if this were available for not just 
base packages, but contributed packages as well.  Personally, I 
find the biggest weakness of the current help system is the fact 
that I must know the name of a function in advance to request help 
on some analysis or proceedure.  Would be nice to start with a 
general idea, category, class, or set of proceedures and move to a 
list of related functions. 

Extending the original idea, wouldn't it be great if there were a list 
as described above that, in addition to listing functions by 
category, also provided package information, availability, version, 
etc for the listed functions.

I recognize that there is probably some overlap with the S-Plus 
guide, and that it in itself is probably a good reference, or at least a 
nice starting point for a simliar R guide.  However, I also suspect 
that quite a lot of the S-Plus functionality listed is not yet 
implemented in R.  Perhaps I am wrong.
