Question

我从Roger Peng的教程中复制了一个r markdown文件。我能够编织到HTML和Word，但编织到pdf的问题。 test.Rmd代码：

My First Knitr Document
===============================

This is some text (i.e. a text chunk).

here is a code chunk
```{r}
set.seed(1)
x <- rnorm(100)
mean(x)
```

点击'knit to pdf'后，错误：

Output created: test.pdf
Error in tools::file_path_as_absolute(output_file) : 
file 'test.pdf' does not exist
Calls: <Anonymous> -> <Anonymous>
In addition: Warning messages:
1: running command '"pdflatex" -halt-on-error -interaction=batchmode 
"test.tex"' had status 1 
2: In readLines(logfile) : incomplete final line found on 'test.log'
Execution halted

当我在cmd（windows）中运行'latexmk -version'时，我得到了：

latexmk: warning: running with administrator privileges
latexmk: The script engine  could not be found
latexmk: Data: scriptEngine="perl.exe"

我的MikTex版本：basic-miktex-2.9.6。

已更新，更准确地说，相同的代码在Mac上运行良好（R版本3.4.0）。
更多信息：我在E盘上安装了RStudio而在C盘上安装了MikTex 同样，我可以使用R Sweave编译pdf。

如果有人能提供帮助，我感激不尽。

如果你点击＆＃34; knit＆＃34;之后的小箭头。你应该能够编织成pdf＆＃34;。然后，R markdown会将正确的YAML标题添加到您的文档中：

＆＃13;

这对我有用。只需插入标题并单击编织。

希望这会有所帮助：）
