There may be such a page somewhere, but it is probably incomplete.  The 
object model in R has methods owned by generics, not by classes.  So 
even if someone wrote a list of all methods that worked on vectors, 
someone else could add a new one without modifying the vector class.

You can ask R what methods are currently visible, e.g.


but it won't show methods in unattached packages.
