_D_e_s_c_r_i_p_t_i_o_n:

     The hypotheses tested in a multiple testing procedure (MTP), can
     be ordered based on the output of that procedure. This function
     orders hypotheses based on adjusted p-values, then unadjusted
     p-values (to break ties in adjusted p-values), and finally test
     statistics (to break remaining ties).

_U_s_a_g_e:

     get.index(adjp, rawp, stat)

_A_r_g_u_m_e_n_t_s:

    adjp: Numeric vector of adjusted p-values.

    rawp: Numeric vector of unadjusted ("raw") marginal p-values.

    stat: Numeric vector of test statistics.

_V_a_l_u_e:

     Numeric vector of indices so that the hypotheses can be ordered
     accroding to significance (smallest p-values and largest test
     statistics first). This function is used in the plot method for
     objects of class 'MTP' to order adjusted p-values for graphical
     summaries. The summary method for objects of class 'MTP' will
     return these indices as its second component.
