[Rd] R CMD check: "Undocumented class" for class created with setOldClass()

Hi all,

in a package, I register two S3 classes (namely ff_vector and ffdf) by 
calling setOldClass() in order to use them as slots in S4 classes. Now, 
R CMD check gives me the warning:

Undocumented S4 classes:
  'ff_vector' 'ffdf'

Is there a way to avoid having to document classes I did not write? Or 
is this intended behaviour?

Best regards,
