[R] hiding/protecting utility functions in .Rprofile

[Michael Friendly]

[Env: WinXp, R 2.9.2]
In my .Rprofile, I define a number of utility functions I'd like to have 
available in my R session, but don't want them
to be *normally* listed by ls(), or more importantly, saved if I save my 
session variables/functions.

How can I do this?
