        An object of class `"profiler"' which is a list with
        function elements

   getFittedPars(): the parameters in `fitted'

   setDefault(varying, params): this is used for changing the
             default settings for profiling. In absence of both
             parameters, the default is set to the original
             fitted parameters with all parameters varying. The
             arguments are

             `varying': a logical, integer or character vector
             giving parameters to be varied.  `params': the
             default value at which profiling is to take place.

   getProfile(varying, params): this can be used in conjunction
             with `setDefault' without any arguments. Alterna-
             tively, the parameters to be varied and the values
             for fixed parameters can be specified using the
             arguments. The arguments are

             `varying': a logical vector giving parameters to
             be varied. This can be omitted if params is a
             named list or numeric vector.

             `params': values for parameters to be held fixed.

             It returns a list with elements

             `parameters': the parameter values for the pro-
             filed optimum.

             `fstat': a profile statistics. See individual
             methods for details.

             `varying': a logical vector indicating parameters
             which were varied.
