_D_e_s_c_r_i_p_t_i_o_n:

     A model function for a model used with the 'Phenobarb' data. This
     function uses compiled C code to improve execution speed.

_U_s_a_g_e:

     phenoModel(Subject, time, dose, lCl, lV)

_A_r_g_u_m_e_n_t_s:

 Subject: an integer vector of subject identifiers.  These should be
          sorted in increasing order.

    time: numeric. A vector of the times at which the sample was drawn
          or the drug administered (hr). 

    dose: numeric. A vector of doses of drug administered (mug/kg). 

     lCl: numeric.  A vector of values of the natural log of the
          clearance parameter according to 'Subject' and 'time'.

      lV: numeric.  A vector of values of the natural log of the
          effective volume of distribution according to 'Subject' and
          'time'.

_D_e_t_a_i_l_s:

     See the details section of 'Phenobarb' for a description of the
     model function that 'phenoModel' evaluates.

_V_a_l_u_e:

     a numeric vector of predicted phenobarbital concentrations.
