[R] invisible functions?

[Peter Malewski]

Hallo,
	I've not worked with R about at least 1/2 year and I wonder
if it is now impossible to read functions like t.test.default within
R?

> methods("t.test")
[1] t.test.default* t.test.formula*

    Non-visible functions are asterisked


and in the NEWS-File I read: 

    o	methods() has a print method which asterisks functions which
	are not user-visible.  methods(class = "foo") now lists
	non-visible functions, and checks that there is a matching generic.

...but perhaps I have to read about the "new classes". Is there a way
to read the hidden functions?
