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

     The 'BD' data frame has 89 rows and 5 columns. There are 89 runs
     with   four buffer components (KCL, MgCl2, KP04, dnTP)
     systematically varied in  a space-filliing design. The response is
     the DNA amplification rate.

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

_F_o_r_m_a_t:

     This data frame contains the following columns: 

     _K_C_l Buffer component. 

     _M_g_C_l_2 Buffer component. 

     _K_P_O_4 Buffer component. 

     _d_N_T_P Buffer component, deoxyribonucleotides. 

     _l_n_y_a Exponential amplification rate on a log scale, i.e. the
          actual amplification  rate.
