_D_e_s_c_r_i_p_t_i_o_n:

     Class of asymptotic Hampel risk which is the trace of the
     asymptotic covariance subject to a given bias bound (bound on
     gross error sensitivity).

_O_b_j_e_c_t_s _f_r_o_m _t_h_e _C_l_a_s_s:

     Objects can be created by calls of the form 'new("asHampel",
     ...)'. More frequently they are created via the generating
     function  'asHampel'.

_S_l_o_t_s:

     '_t_y_p_e': Object of class '"character"':  "trace of asymptotic
          covariance for given bias bound". 

     '_b_o_u_n_d': Object of class '"numeric"':  given positive bias bound. 

_E_x_t_e_n_d_s:

     Class '"asRisk"', directly.
      Class '"RiskType"', by class '"asRisk"'.

_M_e_t_h_o_d_s:

     _b_o_u_n_d 'signature(object = "asHampel")':  accessor function for
          slot 'bound'. 

     _s_h_o_w 'signature(object = "asHampel")'
