     `residuals' is a generic function which extracts model
     residuals from objects returned by modeling functions.

     The abbreviated form `resid' is an alias for `residu-
     als'.  It is intended to encourage users to access
     object components through an accessor function rather
     than by directly referencing an object slot.

     All object classes which are returned by model fitting
     functions should provide a `residuals' method.  (Note
     that the method is `residuals' and not `resid'.)
