问题描述
我只是从Sweave和R开始.在这里，我正在使用R来输出一些数据，并且还试图包含一个绘图.该代码不编织.我有一个来自Web的Sweave示例，可以很好地在RStudio和LaTeX中进行编译.
I am just starting with Sweave and with R. Here I am using R to output some data and I am also trying to include a plot. The code does not sweave. I have one Sweave example from the web that compiles well in RStudio with LaTeX.
\documentclass[a4paper]{article}
\begin{document}
<<echo=TRUE>>=
x <- rnorm(100)
xm <- mean(x)
xm
@
<<echo=FALSE>>=
x <- rnorm(100)
xm <- mean(x)
xm
@
<<echo=TRUE>>=
test.frame<-read.table(file="apples.d",header=T,sep= "")
names(test.frame)
head(test.frame)
class(test.frame)
@
\begin{figure}[htbp]
\begin{center}
\setkeys{Gin}{width=0.5\textwidth}
<<echo=FALSE,fig=TRUE,width=4,height=4>>=
plot(year,value)
@
\end{center}
\end{document}
并且文件apples.d包含:
and the file apples.d contains:
#Number of apples I ate
year value
8 12050 #year 2008
9 15292 #year 2009
10 23907 #year 2010
11 33997 #year 2011
我在做什么错了?
其他相关问题:
Sweave文档是否支持普通的LaTeX bibliography文件.如何进行编译?
Does a Sweave document support normal LaTeX bibliography file. How to do the compilation?
非常感谢...
推荐答案
已纠正多个问题，并以%%%%或####
Several problems corrected, marked by %%%% or ####
\documentclass[a4paper]{article}
\begin{document}
<<echo=TRUE>>=
x <- rnorm(100)
xm <- mean(x)
xm
@
<<echo=FALSE>>=
x <- rnorm(100)
xm <- mean(x)
xm
@
<<echo=TRUE>>=
##### Remove all comments from your data file
test.frame<-read.table(file="apples.d",header=T,sep= "")
names(test.frame)
head(test.frame)
class(test.frame)
@
\begin{figure}[htbp]
\begin{center}
\setkeys{Gin}{width=0.5\textwidth}
<<echo=FALSE,fig=TRUE,width=4,height=4>>=
#### Must tell plot where to get the data from. Could also use test.frame$year
with(test.frame,plot(year,value))
@
\end{center}
\end{figure}
\end{document}
