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

     This sets the edges associated with  one or more GGobi displays
     and its plots. The user can specify whether the edges should be
     drawn as directed or undirected segments.

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

     setDisplayEdges.ggobi(displays, edgeData, directed=FALSE, on = TRUE, .gobi=getDefaultGGobi())

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

displays: a list of 'ggobiDisplay' objects which are to be changed to
          have  the specified edge set ('edgeData') be the associations
          between the points.

edgeData: the dataset providing the edges/connections pairs

directed: a logical value indicating whether the edges should be
          displayed as directed line segments or simple lines.

      on: a logical value indicating whether edges should be drawn or
          not. This can be used to turn off the visible edges. 

   .gobi: the GGobi instance in which to find the displays. This is
          needed if 'displays' is specified using indices  rather than
          'ggobiDisplay' objects. 

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

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

     A list with the same number of elements as displays passed to this
     function. Each element contains a reference to the GGobi dataset
     that was used for edges for the display, or NULL if no edges were
     used.

_N_o_t_e:

     The edge mechanism in GGobi is general and powerful and can be
     difficult to understand  and can be slightly counter-intuitive for
     simple cases.
