r - R：将 Rmarkdown 转换为 PDF

Question

我正在使用 R 编程语言。我正在学习如何使用 Rstudio 将“rmarkdown”转换为 pdf。我在这里关注本教程：https ://rmarkdown.rstudio.com/articles_intro.html

我首先创建了一个新的 Rmarkdown 文件：

然后，我在 Rmarkdown 编辑器中输入了以下文本：

---
output: html_document
---

This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see .

When you click the **Knit** button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:

```{r}
summary(cars)
```

You can also embed plots, for example:

```{r, echo=FALSE}
plot(cars)
```

Note that the `echo = FALSE` parameter was added to the code chunk to prevent printing of the R code that generated the plot.

然后，我点击“编织成 PDF”：

但这不起作用并返回以下消息：

No LaTeX installation detected (LaTeX is required to create PDF output). You should install a LaTeX distribution for your platform: https://www.latex-project.org/get/

  If you are not sure, you may install TinyTeX in R: tinytex::install_tinytex()

  Otherwise consider MiKTeX on Windows - http://miktex.org

  MacTeX on macOS - https://tug.org/mactex/
  (NOTE: Download with Safari rather than Chrome _strongly_ recommended)

  Linux: Use system package manager

有人可以告诉我我做错了什么吗？是否有将 Rmarkdown 转换为 PDF 的简单方法？

谢谢
