_D_e_s_c_r_i_p_t_i_o_n:

     Extract the contents of a slot in a object with a formal (S4)
     class structure.

_U_s_a_g_e:

     object@name

_A_r_g_u_m_e_n_t_s:

  object: An object from a formally defined (S4) class.

    name: The character-string name of the slot.

_D_e_t_a_i_l_s:

     This operator supports the formal classes of package 'methods',
     and is enabled only when 'methods' is loaded (as per default). 
     See 'slot' for further details.

     It is checked that 'object' is an S4 object (see 'isS4'), and it
     is an error to attempt to use '@' on any other object. (There is
     an exception for name '.Data' for internal useonly.)

     If 'name' is not a slot name, an error is thrown.

_V_a_l_u_e:

     The current contents of the slot.

_S_e_e _A_l_s_o:

     'Extract', 'slot'
