\begin{Description}\relax
The \code{zelig} method for the generic \code{plot}
command generates default plots for \code{\LinkA{sim}{sim}} output with
one-observation values in \code{x} and \code{x1}.
\end{Description}
\begin{Usage}
\begin{verbatim}
## S3 method for class 'zelig':
plot(x, xlab = "", user.par = FALSE, ...)
\end{verbatim}
\end{Usage}
\begin{Arguments}
\begin{ldescription}
\item[\code{x}] stored output from \code{\LinkA{sim}{sim}}.  If the \code{x\$x} or
\code{x\$x1} values stored in the object contain more than one
observation, \code{plot.zelig} will return an error.  For linear or
generalized linear models with more than one observation in \code{x\$x}
and optionally \code{x\$x1}, you may use \code{\LinkA{plot.ci}{plot.ci}}.  
\item[\code{xlab}] a character string for the x-axis label for all graphs.
\item[\code{user.par}] a logical value indicating whether to use the default
Zelig plotting parameters (\code{user.par = FALSE}) or
user-defined parameters (\code{user.par = TRUE}), set using the
\code{par} function prior to plotting. 
\item[\code{...}] Additional parameters passed to \code{plot.default}.
Because \code{plot.zelig} primarily produces diagnostic plots, many
of these parameters are hard-coded for convenience and
presentation. 
\end{ldescription}
\end{Arguments}
\begin{Value}
Depending on the class of model selected, \code{plot.zelig} will
return an on-screen window with graphs of the various quantities of
interest.  You may save these plots using the commands described in
the Zelig manual (available at \url{http://gking.harvard.edu/zelig}).
