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

     Plots (for each group in the 'fwdmv' object) the fraction of
     variance explained by the eigenvalues in 'which' and the
     eccentricity of the ellipse from the same two eigenvalues.

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

     fwdmvEccentricityPlot(x, which = c(1, 2), psfrag.labels = FALSE)

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

       x: an 'fwdmv' object.

   which: an integer vector of length 2.  Specifies the eignevalues to
          use in the plot.

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.

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

     an empty list is returned invisibly.
