\begin{Description}\relax
Add box and whiskers
\end{Description}
\begin{Usage}
\begin{verbatim}ggboxplot(plot = .PLOT, aesthetics=list(), ..., data=NULL)\end{verbatim}
\end{Usage}
\begin{Arguments}
\begin{ldescription}
\item[\code{plot}] the plot object to modify
\item[\code{aesthetics}] named list of aesthetic mappings, see details for more information
\item[\code{...}] other options, see details for more information
\item[\code{data}] data source, if not specified the plot default will be used
\end{ldescription}
\end{Arguments}
\begin{Details}\relax
Aesthetic mappings that this grob function understands:

\Itemize{
\item \code{x}:x position (required)
\item \code{y}:y position (required)
\item \code{weight}: observation weights
}

These can be specified in the plot defaults (see \code{\LinkA{ggplot}{ggplot}}) or
in the \code{aesthetics} argument.  If you want to modify the position
of the points or any axis options, you will need to add a position scale to
the plot.  These functions start with \code{ps}, eg.
\code{\LinkA{pscontinuous}{pscontinuous}} or \code{\LinkA{pscategorical}{pscategorical}}

Other options:

\Itemize{
\item \code{breaks}:how to break up the x axis (only used if not already a factor)
\item \code{orientation}: whether boxplots should be horizontal or vertical.
If missing will automatically decide based on which variable is a factor.
\item other arguments passed \code{\LinkA{boxplot}{boxplot}}
}
