我正在尝试使用 beamer + sweave 对 ggplot2 图形进行演示。有些幻灯片应该有两列;左边的是代码,右边的是生成的图形。这是我尝试过的,
\documentclass[xcolor=dvipsnames]{beamer}
\usepackage{/Library/Frameworks/R.framework/Resources/share/texmf/tex/latex/Sweave}
\usepackage[english]{babel}
\usepackage{tikz}
\usepackage{amsmath,amssymb}% AMS standards
\usepackage{listings}
\usetheme{Madrid}
\usecolortheme{dove}
\usecolortheme{rose}
\SweaveOpts{pdf=TRUE, echo=FALSE, fig=FALSE, eps=FALSE, tidy=T, width=4, height=4}
\title{Reproducible data analysis with \texttt{ggplot2} \& \texttt{R}}
\subtitle{subtitle}
\author{Baptiste Augui\'e}
\date{\today}
\institute{Here}
\begin{document}
\begin{frame}[fragile]
\frametitle{Some text to show the space taken by the title}
\begin{columns}[t] \column{0.5\textwidth}
Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat.

\column{0.5\textwidth}
\begin{figure}[!ht]
\centering
<<fig=TRUE>>=
grid.rect(gp=gpar(fill="slateblue"))
@
\end{figure}
\end{columns}
\end{frame}
\begin{frame}[fragile]
\frametitle{Some text to show the space taken by the title}
\begin{columns}[t]
\column{0.5\textwidth}
<<echo=TRUE,fig=FALSE>>=
library(ggplot2)
p <-
qplot(mpg, wt, data=mtcars, colour=cyl) +
theme_grey(base_family="Helvetica")
@
\column{0.5\textwidth}
\begin{figure}[!ht]
\centering
<<fig=TRUE>>=
print(p)
@
\end{figure}
\end{columns}
\end{frame}
\end{document}
和输出的两页。
我对这个输出有两个问题:
有任何想法吗?
谢谢。
最佳答案
keep.source=TRUE
在 SweaveOpts 中。更多花式控制,见fancyvrb
和 Sweave 手册的 FAQ #9。 \setkeys{Gin}{width=1.0\textwidth}
设置这是一个轻微的修改:
... snip ...
\SweaveOpts{pdf=TRUE, echo=FALSE, fig=FALSE, eps=FALSE, tidy=T, width=4, height=4, keep.source=TRUE}
\title{Reproducible data analysis with \texttt{ggplot2} \& \texttt{R}}
... snip ...
\begin{document}
\setkeys{Gin}{width=1.1\textwidth}
... snip...
<<echo=TRUE,fig=FALSE>>=
library(ggplot2)
p <-
qplot(mpg,
wt,
data=mtcars,
colour=cyl) +
theme_grey(base_family=
"Helvetica")
