\Header{allCoef}{Extract Coefficients from a Set of Objects}
\keyword{models}{allCoef}
\begin{Description}\relax
The extractor function is applied to each object in \code{...}, with
the result being converted to a vector. A \code{map} attribute is
included to indicate which pieces of the returned vector correspond to
the original objects in \code{dots}.
\end{Description}
\begin{Usage}
\begin{verbatim}
allCoef(..., extract)
\end{verbatim}
\end{Usage}
\begin{Arguments}
\begin{ldescription}
\item[\code{...}] objects to which \code{extract} will be applied. Generally
these will be model components, such as \code{corStruct} and
\code{varFunc} objects.
\item[\code{extract}] an optional extractor function. Defaults to \code{coef}.
\end{ldescription}
\end{Arguments}
\begin{Value}
a vector with all elements, generally coefficients, obtained by
applying \code{extract} to the objects in \code{...}.
