[R] How do I view hidden methods?

[Kevin Wright]

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?
