How can one discover or list all available built-in objects?
Depends what you mean with `built-in'...

LETTERS is apparently a built-in character vector. ls() and objects () only lists the ones I've created.
More precisely, it lists the objects in the global environment.
Is there a function that lists all available built-in objects?
R> search()
will show you the search path and in particular all packages that are
currently attached. Using
R> ls("package:base")
you could list all objects in the base packages which includes LETTERS.
For example, "pi" is another built-in, but "e" is not.
But "exp" is. So R> exp(1) will give you "e". Z
A means to list them would be nice. Regards, - Robert
