如何使用RStudio用Stata命令编写RMarkdown文件？

我的问题已在标题中解释。我尝试编译一个示例 .Rmd 我在这里找到：http://www.ssc.wisc.edu/~hemken/Stataworkshops/Stata%20and%20R%20Markdown/ http://www.ssc.wisc.edu/~hemken/Stataworkshops/Stata%20and%20R%20Markdown/除了在网上查找各种资源也无济于事。虽然我的资源 Doug 能够编译 RMarkdown，但我收到下面的 MWE 错误。

MWE 为：

```{r, echo=FALSE, message=FALSE}
require(knitr)
statapath <- "/Applications/Stata/Stata.app"
opts_chunk$set(engine="stata", engine.path=statapath, comment="")
```

### Descriptive Statistics
A simple example.
```{r}
sysuse auto
summarize
```

RStudio 控制台的输出/错误是：

您链接到的页面指向这一页 http://www.stata.com/support/faqs/mac/advanced-topics/#startup。那里写道：“例如，如果 Stata 安装在 /Applications/Stata/ 中，则 Stata 可执行文件的路径为 /Applications/Stata/Stata.app/Contents/MacOS/”，并且它们提供了适当的链接所有不同风格的 Stata。此外，您需要引用可执行文件，而不是它所在的文件夹。如果我按如下方式更改您的 MWE，一切都对我有用（请注意，我使用 Stata-SE；您可能需要为您的系统更改此设置）。
