Extract Model Fitted Values

Description:

     'fitted' is a generic function which extracts fitted values from
     objects returned by modeling functions.  'fitted.values' is an
     alias for it.

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

     Methods can make use of 'napredict' methods to compensate for the
     omission of missing values.  The default, 'lm' and 'glm' methods
     do.

Usage:

     fitted(object, ...)
     fitted.values(object, ...)

Arguments:

  object: an object for which the extraction of model fitted values is
          meaningful.

     ...: other arguments.

Value:

     Fitted values extracted from the object 'x'.
