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

     Produces a plot of the likelihood ratio of transformation
     parameters during all steps of the forward search.

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

     fwdtrLrPlot(x, psfrag.labels = FALSE)

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

       x: a 'fwdtr' object. 

psfrag.labels: a logical value.  If 'TRUE' then the x, y, and main
          labels are set to "xlab", "ylab", and "main" for replacement
          via the psfrag utility.

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

     The horizontal lines drawn in the plot refer to the 95% and 99%
     quantiles of the associated chisquare distribution.

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

     an empty list is invisibly returned.
