Я пытаюсь создать приложение с кодом, используя инструкции с сайта Иихуэй ниже:
https://bookdown.org/yihui/rmarkdown-cookbook/code-appendix.html
Проблема в том, что я ничего не получаю, ничего происходит при предварительном просмотре кода в RStudio. Одна вещь, которую я заметил, это то, что код knitr::all_labels() возвращает NULL, хотя я назвал все 30+ блоков в моем Rnotebook. Также я смог создать внешний файл с purl, который является последней строкой. Я пытался создать репрекс с базовым c стартовым Rnotebook, но репрекс не встроил в RStudio, поэтому я собираюсь вставить то, что попробовал.
Спасибо!
Код ... извините, мне пришлось убрать галочки, чтобы я мог вставить все куски кода вместе.

This is an [R Markdown](http://rmarkdown.rstudio.com) Notebook. When you execute code within the notebook, the results appear beneath the code.
Try executing this chunk by clicking the *Run* button within the chunk or by placing your cursor inside it and pressing *Ctrl+Shift+Enter*.
{r test}
plot(cars)
Add a new chunk by clicking the *Insert Chunk* button on the toolbar or by pressing *Ctrl+Alt+I*.
When you save the notebook, an HTML file containing the code and output will be saved alongside it (click the *Preview* button or press *Ctrl+Shift+K* to preview the HTML file).
The preview shows you a rendered HTML copy of the contents of the editor. Consequently, unlike *Knit*, *Preview* does not run any R code chunks. Instead, the output of the chunk when it was last run in the editor is displayed.
