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

     Expand a tframe or tframed object.

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

         tfexpand(x, add.start=0, add.end=0)
         tfexpand(x, start, end)
         tfexpand.tframe(x, add.start=0, add.end=0)
         tfexpand.tframe(x, add.start=0, add.end=0)
         tfexpand.tframe(x, add.start=0, add.end=0)

         tftruncate(x, start=NULL, end=NULL)
         tftruncate(x, start=NULL, end=NULL)
         tftruncate.tframe(x, start=NULL, end=NULL)
         tftruncate.tframe(x, start=NULL, end=NULL)
         tftruncate.tframe(x, start=NULL, end=NULL)

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

       x: A tframe or tframed object.

   start: An integer indicating the position at which the new tframe is
          to start. 

     end: An integer indicating the position at which the new tframe is
          to end. 

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

     These functions are like tfwindow but use position indicators
     (rather  than dates) and work with the tframe or tframed data.
     They are low level utilities for other functions.

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

     A tframe or tframed object.

_S_e_e _A_l_s_o:

     `tfwindow' `tframed'

_E_x_a_m_p_l_e_s:

         tframe(tftruncate(ts(rnorm(100), start=c(1982,1), frequency=12), start=5))
