[R] discovery (was: data.frame to character)

How can one discover or list all available built-in objects?

LETTERS is apparently a built-in character vector.  ls() and objects 
() only lists the ones I've created.  Is there a function that lists  
all available built-in objects?

For example, "pi" is another built-in, but "e" is not.  A means to  
list them would be nice.
