help! a urgent question

Dear Sir/Madam,
 
I am doing a project related to R. 
However, it is always difficult find some R functions.
The R user guide seems not complete. 
Is there any free document about all R functions ?
Who knows ? please help me.
My email is myzhaogong at yahoo.com 


Thank you very much

Perhaps if you provided some insight into what exactly it is you are
looking to do, we can provide some specific guidance.

The R Manuals are typically available in your installation, accessible
via help.start().

However they are also online at the main R site:

http://www.r-project.org/

Along the left hand side of the page under "Documentation", there are
several links to available manuals, user contributed docs, FAQ's, etc.

HTH,

Marc Schwartz
