Я работаю с языком программирования R. Я учусь конвертировать «rmarkdown» в pdf с помощью Rstudio. Я следую этому уроку здесь: https://rmarkdown.rstudio.com/articles_intro.html

Я впервые создал новый файл Rmarkdown:

Затем я ввел следующий текст в редактор Rmarkdown:

 ---
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.
 

Затем я нажал «Связать в PDF».:

But this did not work and returned the following message:

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
 

Может кто-нибудь, пожалуйста, показать мне, что я делаю не так? Есть ли простой способ конвертировать Rmarkdown в PDF?

Спасибо
