\Header{logLik}{Extract Log-Likelihood}
\keyword{models}{logLik}
\begin{Description}\relax
This function is generic; method functions can be written to handle
specific classes of objects. Classes which already have methods for
this function include: \code{corStruct}, \code{gls}, \code{lm},
\code{lme}, \code{lmList}, \code{lmeStruct}, \code{reStruct}, and
\code{varFunc}.\end{Description}
\begin{Usage}
\begin{verbatim}
logLik(object, ...)
\end{verbatim}
\end{Usage}
\begin{Arguments}
\begin{ldescription}
\item[\code{object}] any object from which a log-likelihood value, or a
contribution to a log-likelihood value, can be extracted.
\item[\code{...}] some methods for this generic function require additional
arguments.
\end{ldescription}
\end{Arguments}
\begin{Value}
will depend on the method function used; see the appropriate
documentation.\end{Value}
