     A linear mixed-effects structure is a list of model
     components representing different sets of parameters in
     the linear mixed-effects model. An `lmeStruct' list
     must contain at least a `reStruct' object, but may also
     contain `corStruct' and `varFunc' objects. `NULL' argu-
     ments are not included in the `lmeStruct' list.

reStruct: a `reStruct' representing a random effects struc-
          ture.

corStruct: an optional `corStruct' object, representing a
          correlation structure. Default is `NULL'.

varStruct: an optional `varFunc' object, representing a
          variance function structure. Default is `NULL'.

_V_a_l_u_e_:

     a list of model components determining the parameters
     to be estimated for the associated linear mixed-effects
     model.
