R help - May 2003 - How do I view hidden methods?

I'm using R 1.7.0 on Windows 2000.

I'm a long-time user of R, but am experiencing frustration because
I can't figure out how to view the function definition of a non-exported 
method.  (I know I can go view the source code or the code in the library
directory
but I am trying to view the function inside the R environment.

In particular,

library(mva)
biplot.princomp
Error: Oject "biplot.princomp" not found.


Right now I don't like hidden methods, but maybe someone can explain
the value of hiding functions from the user?

So they can't be called directly, but only via UseMethod.
You can see the function with

getS3method("biplot","princomp")
