Linear Mixed-Effects Structure

Description:

     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' arguments are not included in the 'lmeStruct'
     list.

Usage:

     lmeStruct(reStruct, corStruct, varStruct)

Arguments:

reStruct: a 'reStruct' representing a random effects structure.

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'.

Value:

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