![由于“menukeys”包,需要额外的 \endgroup.\begin{document}](https://linux22.com/image/423420/%E7%94%B1%E4%BA%8E%E2%80%9Cmenukeys%E2%80%9D%E5%8C%85%EF%BC%8C%E9%9C%80%E8%A6%81%E9%A2%9D%E5%A4%96%E7%9A%84%20%5Cendgroup.%5Cbegin%7Bdocument%7D.png)
我被错误消息“Extra \endgroup.\begin{document}”困住了。当我使用 menukeys 包时,会发生此错误。一个简短的工作示例是

\begin{document}
The use of \rfunc{panel} defines how different groups will be represented on the graph. When say \texttt{xyplot(y$\sim$x|z)} is entered on R console, R execute: \texttt{xyplot(y$\sim$x|z, panel=penal.xyplot)}, where \rfunc{panel.xyplot} is the default panel function. The \rfunc{lattice} package contains a number of predefined function that can call the other panel function, depending on the argument used.
\begin{lstlisting}
> xyplot(mpg ~ wt | factor(vs, levels = c(0, 1),
+ labels = c("vs = 0", "vs = 1")), data = mtcars,
+ type = c("p"), pch = 19,
+ panel = function( ... ){
+ panel.xyplot( ... )
+ panel.grid(... , h = -1, v = -1)
+ panel.loess( ... )} )
\end{lstlisting}
