\HeaderA{panel.densityplot}{Default Panel Function for densityplot}{panel.densityplot}
\keyword{dplot}{panel.densityplot}
\begin{Description}\relax
This is the default panel function for \code{densityplot}.
\end{Description}
\begin{Usage}
\begin{verbatim}
panel.densityplot(x, darg, plot.points = "jitter", ref = FALSE,
                  col, col.line, jitter.amount, ...)
\end{verbatim}
\end{Usage}
\begin{Arguments}
\begin{ldescription}
\item[\code{x}] data points for which density is to be estimated
\item[\code{darg}] list of arguments to be passed to the \code{density}
function. Typically, this should be a list with zero or more of the
following components : \code{bw}, \code{adjust}, \code{kernel},
\code{window}, \code{width}, \code{give.Rkern}, \code{n},
\code{from}, \code{to}, \code{cut}, \code{na.rm} (see
\code{\LinkA{density}{density}} for details)

\item[\code{plot.points}] logical specifying whether or not the data points should be plotted
along with the estimated density.  Alternatively, a character string
specifying how the points should be plotted.  Meaningful values are
\code{"rug"}, in which case \code{\LinkA{panel.rug}{panel.rug}} is used to plot
a \sQuote{rug}, and \code{"jitter"}, in which case the points are
jittered vertically to better distinguish overlapping points.

\item[\code{ref}] logical, whether to draw x-axis 
\item[\code{col}] color for points and line
\item[\code{col.line}] color for line, overrides col 
\item[\code{jitter.amount}] when \code{plot.points="jitter"}, the value to use as the
\code{amount} argument to \code{\LinkA{jitter}{jitter}}.

\item[\code{...}] extra grahical parameters
