     Create a profiler object for the model object `fitted'.

     profiler(fitted, ...)

_A_r_g_u_m_e_n_t_s_:

  fitted: the original fitted model object.

     ...: Additional parameters. See documentation on indi-
          vidual methods.

_V_a_l_u_e_:

     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.
