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

     Create Tukey Mean-Difference Plots from a trellis object returned
     by `xyplot' and `qq'

_U_s_a_g_e:

     tmd(object, xlab = "mean", ylab = "difference", ...)

_A_r_g_u_m_e_n_t_s:

  object: An object of class ``trellis'' returned by `xyplot' or `qq' 

    xlab: x label

    ylab: y label

     ...: other arguments

_D_e_t_a_i_l_s:

     The Tukey Mean-difference plot is produced by modifying the (x,y)
     values of each panel as follows: the new coordinates are given by
     `x=(x+y)/2, y=y-x'.

     Most arguments given to produce object are transmitted to `tmd',
     with the notable exceptions of `aspect' and `scales'. (This
     behaviour is different from S-Plus.)

_V_a_l_u_e:

     An object of class ``trellis''.
