\HeaderA{panel.bwplot}{Default Panel Function for bwplot}{panel.bwplot}
\keyword{dplot}{panel.bwplot}
\begin{Description}\relax
This is the default panel function for \code{bwplot}.
\end{Description}
\begin{Usage}
\begin{verbatim}
panel.bwplot(x, y, box.ratio = 1,
             horizontal = TRUE,
             pch, col, cex, 
             font, fontfamily, fontface, 
             fill, varwidth = FALSE,
             ...,
             levels.fos,
             stats = boxplot.stats,
             coef = 1.5,
             do.out = TRUE)
\end{verbatim}
\end{Usage}
\begin{Arguments}
\begin{ldescription}
\item[\code{x, y}] numeric vector or factor. Boxplots drawn for each unique value of
\code{y} (\code{x}) if \code{horizontal} is \code{TRUE} (\code{FALSE})
\item[\code{box.ratio}] ratio of box height to inter box space
\item[\code{horizontal}] logical. If FALSE, the plot is \sQuote{transposed} in the sense that
the behaviours of x and y are switched. x is now the
\sQuote{factor}.  Interpretation of other arguments change
accordingly. See documentation of \code{\LinkA{bwplot}{bwplot}} for a fuller
explanation.

\item[\code{pch, col, cex, font, fontfamily, fontface}] graphical parameters
controlling the dot.  \code{pch="|"} is treated specially, by
replacing the dot with a line (similar to \code{\LinkA{boxplot}{boxplot}})

\item[\code{fill}] color to fill the boxplot
\item[\code{varwidth}] logical. If TRUE, widths of boxplots are proportional
to the number of points used in creating it.
\item[\code{stats}] a function, defaulting to \code{\LinkA{boxplot.stats}{boxplot.stats}},
that accepts a numeric vector and returns a list similar to the
return value of \code{boxplot.stats}.  The function must accept
arguments \code{coef} and \code{do.out} even if they do not use
them (a \code{...} argument is good enough).  This function is
used to determine the box and whisker plot.  
\item[\code{coef, do.out}] passed to \code{stats}
\item[\code{levels.fos}] numeric values corresponding to positions of the
factor or shingle variable.  For internal use. 
\item[\code{...}] further arguments, ignored.

\end{ldescription}
\end{Arguments}
\begin{Details}\relax
Creates Box and Whisker plot of \code{x} for every level of
\code{y} (or the reverse if \code{horizontal=FALSE}).  By default, the
actual boxplot statistics are calculated using \code{boxplot.stats}.
Note that most arguments controlling the display can be supplied to
the high-level \code{bwplot} call directly.
