我在運行最小knitrrnw示例中出現問題Rstudio。我從his github knitr最小示例不顯示數字

\title{A Minimal Demo of knitr} 

\author{Yihui Xie} 

\maketitle 
You can test if \textbf{knitr} works with this minimal demo. OK, let's 
get started with some boring random numbers: 

<<boring-random>>= 
set.seed(1121) 
(x=rnorm(20)) 
mean(x);var(x) 
@ 

The first element of \texttt{x} is \Sexpr{x[1]}. Boring boxplots 
and histograms recorded by the PDF device: 

<<boring-plots, fig.width=4, fig.height=4, out.width='.4\\linewidth'>>= 
## two plots side by side (option fig.show='hold') 
par(mar=c(4,4,.1,.1),cex.lab=.95,cex.axis=.9,mgp=c(2,.7,0),tcl=-.3,las=1) 
boxplot(x) 
hist(x,main='') 
@ 

Do the above chunks work? You should be able to compile the \TeX{} 
document and get a PDF file like this one: \url{https://github.com/yihui/knitr/releases/download/doc/knitr-minimal.pdf}. 
The Rnw source of this document is at \url{https://github.com/yihui/knitr/blob/master/inst/examples/knitr-minimal.Rnw}. 
\end{document}

這讓我這個當我「編譯PDF」下面的小例子：

只能預警的sI得到如下：

編輯：這似乎與數字子目錄不創建，我得到與人物Rplot.pdf ......

它適用於我。也許這個figure subdir的創建失敗了。 – user2554330

事實上，它似乎我沒有子文件夾...任何想法？但即使我手動創建它的情節也不會保存在那裏 – statquant

我解決它通過丟棄Rstudio。只需使用R) knit('example.Rnw')然後bash) pdflatex example.tex
