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

     A class which represents a _Membership Function_ to determine the
     membership of a numeric value to  the Low discrete label. The
     result depends on the center and width values.

_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("LowExpressionLevel")'.

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


     '_c_e_n_t_e_r': Object of class '"numeric"'. Represents the peak point
          in the function curve. 

     '_w_i_d_t_h': Object of class '"numeric"'. Represents the length of
          values lower than 1 and greater than 0 in the function curve. 

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

     Class '"ExpressionLevel"', directly.

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


     _s_e_t_V_a_l_u_e_s 'signature(object = "LowExpressionLevel", values =
          "numeric")': Establishes the center and width slots of
          the object, given a vector of numeric values.

     _c_o_m_p_u_t_e_M_e_m_b_e_r_s_h_i_p 'signature(object = "LowExpressionLevel", x =
          "numeric")': Returns a value in the [0,1] interval, which
          represents the membership to the Low discrete label.
