_D_e_s_c_r_i_p_t_i_o_n:

     The 'Indometh' data frame has 66 rows and 3 columns of data on the
     pharmacokinetics of indomethicin.

_U_s_a_g_e:

     Indometh

_F_o_r_m_a_t:

     This data frame contains the following columns:

     _S_u_b_j_e_c_t an ordered factor with containing the subject codes.  The
          ordering is according to increasing maximum response.

     _t_i_m_e a numeric vector of times at which blood samples were drawn
          (hr).

     _c_o_n_c a numeric vector of plasma concentrations of indomethicin
          (mcg/ml).

_D_e_t_a_i_l_s:

     Each of the six subjects were given an intravenous injection of
     indomethicin.
