Can we comment out RMarkdown so that it's not included in the exported HTML?-CodePudding

I am trying to comment out a section of code in my RMarkdown. I know that I can use the  syntax to add comments, but these comments still appear in the rendered HTML (although hidden). Is there a way to create real comments that are ignored during rendering and don't appear in the exported document source code?

CodePudding user response：

You could specify with echo to code lines to show in your output like this:

---
date: "2022-12-13"
output: html_document
---

```{r echo=2:4}
# This comment should not be shown
rnorm(3)
# But keep this comment in output html
```

Output:

As you can see it doesn't show the first comment.

CodePudding user response：

You can wrap everything in ~~~{=comment} ... ~~~ to get it ignored:

Normal text

~~~{=comment}
this will be ignored

This, too!
~~~

No longer in a comment.
