R devel - Apr 2010 - generic '[' for a non-exported class

Hi all,
I define a S4 class 'foo'. I define '[' and '[<-' for
it.
I do not want to export foo, so I do not put it in NAMESPACE.
I do not want to export '[' and '[<-' either (since the user
can not use
foo, no raison to give him access to '[' for foo).

But R CMD check does not agree with me and report an error:
Undocumented S4 methods:
  generic '[' and siglist 'foo'
  generic '[<-' and siglist 'foo'


Any solution ?

You can document these on an internal API Rd page.  Create an Rd file 
like yourPkg-internal-api.Rd and add the appropriate \alias{} lines to it.
