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

     Data from an experiment in which a single-cylinder engine was run
     with ethanol to see how the NOx concentration in the exhaust
     depended on the compression ratio and the equivalence ratio.

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

     data(nox)

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

     A data frame containing 88 observations on the following
     variables.

       `nox'   NOx concentration in exhaust.
       `comp'  Compression ratio.
       `equi'  Equivalence ratio.
