_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.

     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'
