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

     Create an `lmeLevel' object from its components

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

     lmeLevel(precision, groups, columns, modelMatrix)

_A_r_g_u_m_e_n_t_s:

precision: A `pdMat' object representing the relative precision matrix
          for the random effects.  This argument is missing in calls to
          generate the `lmeLevel' for the fixed-effects terms and for
          the response.

  groups: The grouping factor.  This argument is missing in calls to
          generate the `lmeLevel' for the fixed-effects terms and for
          the response.

 columns: integer vector: the columns in `modelMatrix' corresponding to
          this level of random or fixed effects.

modelMatrix: a model matrix: the `original' slot of the containing
          `reStruct' object

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

     An `lmeLevel' object contains information on one level of
     random-effects terms or the fixed-effects terms or the response in
     a linear mixed-effects structure.

_V_a_l_u_e:

     An `lmeLevel' object.

_S_e_e _A_l_s_o:

     `lmeLevel-class', `pdMat-class', `reStruct-class'
