\end{Description}
\begin{Usage}
\begin{verbatim}
panel.qqmath(x, f.value = NULL,
             distribution = qnorm,
             qtype = 7,
             groups = NULL, ...)
\end{verbatim}
\end{Usage}
\begin{Arguments}
\begin{ldescription}
\item[\code{x}] vector (typically numeric, coerced if not) of data values to be used
in the panel.

\item[\code{f.value, distribution}] Defines how quantiles are calculated.  See \code{\LinkA{qqmath}{qqmath}} for
details.

\item[\code{qtype}] The \code{type} argument to be used in \code{\LinkA{quantile}{quantile}}

\item[\code{groups}] An optional grouping variable.  Within each panel, one Q-Q plot is
produced for every level of this grouping variable, differentiated

\item[\code{...}] further arguments, often graphical parameters.
