我从 Roger Peng 的教程中复制了一个降价文件。我能够编织到 html 和 Word,但在编织到 pdf 时遇到了问题。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:

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

我的会话信息:

我的 MikTex 版本:basic-miktex-2.9.6。

更新,更准确地说,相同的代码在 mac 上运行良好(虽然 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。
另外,我可以使用 R Sweave 编译 pdf。

如果有人可以提供帮助,我将不胜感激。

如果您单击“编织”旁边的小箭头,您应该能够“编织到 pdf”。然后,R markdown 会将正确的 YAML 标头添加到您的文档中:

---
output:
  pdf_document: default
---
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)
```  

这对我有用。只需插入标题并单击编织。

下一次:请快速查看文档

希望这可以帮助 :)
