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

     Experiment investigating the inhibition of photosynthesis in
     response to two synthetic  photosystem II inhibitors, the
     herbicides diuron and bentazone. The effect of oxygen consumption
     of thylakoid membranes (chloroplasts) from spinach was measured
     after incubation with the synthetic inhibitors, resulting in 5
     dose-response curves.

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

     data(spinach)

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

     A data frame with 105 observations on the following 3 variables:

     _C_U_R_V_E a numeric vector.

     _H_E_R_B_I_C_I_D_E a character vector.

     _D_O_S_E a numeric vector.

     _S_L_O_P_E a numeric vector.

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

     CURVE denotes a total of five independent assays with two
     herbicides. HERBICIDE denotes the names of the herbicides. DOSE is
     the concentration of the herbicides muMol and SLOPE is  the oxygen
     consumption of thylakoid membranes.
