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

     Plots the normal inverse Gaussian Shape Triangle.

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

     nigShapeTriangle(object, add = FALSE, labels = TRUE, ...)

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

  object: an object of class '"fDISTFIT"' as returned by the function
          'nigFit'. 

     add: a logical value. Should another point added to the NIG shape
          triangle? By default FALSE, a new plot will be created. 

  labels: a logical flag by default 'TRUE'.  Should the logarithm of
          the density be returned? 

     ...: arguments to be passed to the function 'integrate'. 

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

     displays the parameters of fitted distributions in the NIG shape
     triangle.

_A_u_t_h_o_r(_s):

     David Scott for code implemented from R's  contributed package
     'HyperbolicDist'.
