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

     `grecip' calculates the dyadic reciprocity of the elements of
     `dat' selected by `g'.

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

     grecip(dat, g=NULL)

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

     dat: An adjacency matrix, or stack thereof 

       g: A vector indicating which matrices to evaluate (optional) 

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

     The dyadic reciprocity of a graph is the proportion of dyads which
     are symmetric; this is computed and returned by `grecip' for the
     graphs indicated.  Note that the dyadic reciprocity is distinct
     from the tie reciprocity, which is the proportion of edges which
     are reciprocated.

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

     The graph reciprocity value(s)
