\begin{Description}\relax
This method function extracts the coefficients associated with the
correlation structure represented by \code{object}.
\end{Description}
\begin{Usage}
\begin{verbatim}
## S3 method for class 'corStruct':
coef(object, unconstrained, ...)
## S3 method for class 'corStruct':
coef(object, ...) <- value
\end{verbatim}
\end{Usage}
\begin{Arguments}
\begin{ldescription}
\item[\code{object}] an object inheriting from class \code{corStruct},
representing a correlation structure.
\item[\code{unconstrained}] a logical value. If \code{TRUE} the coefficients
are returned in unconstrained form (the same used in the optimization
algorithm). If \code{FALSE} the coefficients are returned in
"natural", possibly constrained, form. Defaults to \code{TRUE}.
\item[\code{value}] a vector with the replacement values for the coefficients
associated with \code{object}. It must be a vector with the same length
of \code{coef\{object\}} and must be given in unconstrained form.
\item[\code{...}] some methods for this generic require additional
arguments.  None are used in this method.
\end{ldescription}
\end{Arguments}
\begin{Value}
a vector with the coefficients corresponding to \code{object}.
\end{Value}
\begin{Section}{SIDE EFFECTS}
On the left side of an assignment, sets the values of the coefficients
of \code{object} to \code{value}. \code{Object} must be initialized (using
\code{Initialize}) before new values can be assigned to its
coefficients.
