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

     Retrieve or set the incidence matrix representation of a graph

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

     incidenceMatrix(object, ...)
     incidenceMatrix(x, force = TRUE)<- value

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

  object: a graph object from which the representation should be
          retrieved

     ...: additional parameters to be used when retrieving the
          representation

       x: a graph object in which the representation should be set

   force: a logical value telling whether the representation should be
          set even if this amounts to changing the graph

   value: an object of class '"incidenceMatrix"' containing the
          representation to be set

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

     The functions 'incidenceMatrix' and 'incidenceMatrix<-' are
     generic.

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

     The function 'incidenceMatrix' returns an object of  class
     '"incidenceMatrix"' containing the incidence matrix representation
     to be retrieved. The function 'incidenceMatrix<-' returns a graph
     object in which the incidence matrix representation has been set.

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

     Jens Henrik Badsberg, Claus Dethlefsen, Luca La Rocca

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

     'incidenceMatrix-class' and 'generalGraph-class'
