\begin{Description}\relax
A linear mixed-effects structure is a list of model components
representing different sets of parameters in the linear mixed-effects
model. An \code{lmeStruct} list must contain at least a
\code{reStruct} object, but may also contain \code{corStruct} and
\code{varFunc} objects. \code{NULL} arguments are not included in the
\code{lmeStruct} list.
\end{Description}
\begin{Usage}
\begin{verbatim}
lmeStruct(reStruct, corStruct, varStruct)
\end{verbatim}
\end{Usage}
\begin{Arguments}
\begin{ldescription}
\item[\code{reStruct}] a \code{reStruct} representing a random effects
structure.
\item[\code{corStruct}] an optional \code{corStruct} object, representing a
correlation structure. Default is \code{NULL}.
\item[\code{varStruct}] an optional \code{varFunc} object, representing a
variance function structure. Default is \code{NULL}.
\end{ldescription}
\end{Arguments}
\begin{Value}
a list of model components determining the parameters to be estimated
for the associated linear mixed-effects model.
