_D_e_s_c_r_i_p_t_i_o_n:

     This method function updates each element of 'object', allowing
     the access to 'data'.

_U_s_a_g_e:

     ## S3 method for class 'modelStruct':
     update(object, data, ...)

_A_r_g_u_m_e_n_t_s:

  object: an object inheriting from class 'modelStruct', representing a
          list of model components, such as 'corStruct' and 'varFunc'
          objects.

    data: a data frame in which to evaluate the variables needed for
          updating the elements of 'object'.

     ...: some methods for this generic require additional arguments. 
          None are used in this method.

_V_a_l_u_e:

     an object similar to 'object' (same class, length, and names), but
     with updated elements.

_N_o_t_e:

     This method function is primarily used within model fitting
     functions, such as 'lme' and 'gls', that allow model components
     such as variance functions.
