Answer 1

Yes, you can access the output format via knitr::opts_knit$get("rmarkdown.pandoc.to"). This will return a string with the target output format. Here's an example:

---
title: "Untitled"
output: html_document
---

```{r}
library(knitr)
opts_knit$get("rmarkdown.pandoc.to")
```

This returns "html" for html_document, "docx" for word_document, and "latex" for pdf_document. So to answer your question you can do something like:

html <- knitr::opts_knit$get("rmarkdown.pandoc.to") == "html"
