_D_e_s_c_r_i_p_t_i_o_n:

     These functions set and query a _comment_ attribute for any R
     objects.  This is typically useful for 'data.frame's or model
     fits.

     Contrary to other 'attributes', the 'comment' is not printed (by
     'print' or 'print.default').

_U_s_a_g_e:

     comment(x)
     comment(x) <- value

_A_r_g_u_m_e_n_t_s:

       x: any R object

   value: a 'character' vector

_S_e_e _A_l_s_o:

     'attributes' and 'attr' for "normal" attributes.

_E_x_a_m_p_l_e_s:

     x <- matrix(1:12, 3,4)
     comment(x) <- c("This is my very important data from experiment #0234",
                     "Jun 5, 1998")
     x
     comment(x)
