     The 'IGF' data frame has 237 rows and 3 columns.

_F_o_r_m_a_t:

     This data frame contains the following columns:

     _L_o_t an ordered factor giving the radioactive tracer lot.

     _a_g_e a numeric vector giving the age (in days) of the radioactive
          tracer.

     _c_o_n_c a numeric vector giving the estimated concentration of IGF-I
          protein (ng/ml)

_D_e_t_a_i_l_s:

     Davidian and Giltinan (1995) describe data obtained during quality
     control radioimmunoassays for ten different lots of radioactive
     tracer used to calibrate the Insulin-like Growth Factor (IGF-I)
     protein concentration measurements.
