Comment out text in R Markdown (Rmd file)

In an R Markdown (.Rmd) file, how do you comment out unused text? I'm not referring to the text in the R code chunk, but the general texts, like % in LaTex for example.

We can use

# Converted R Markdown code chunk in .Rmd file
    
`r ''````{r stream, eval=FALSE}
strm <- FastqStreamer("a.fastq.gz")
repeat {
  fq <- yield(strm)
  if (length(fq) == 0)
    break
  ## process chunk
}

This is found from a https://github.com/rstudio/rmarkdown-book/blob/main/03-documents.Rmd bookdown which is used we want a code block to not execute while knitting.

Does it solves your problem??? if you have any questions please let me know.

You can always turn off code by putting it within an if(F){} statement.

After drag the lines you want to make comment, press SHIFT+CMD+C (macOS), SHIFT+CTRL+C (Windows). This is the shortcut of R Markdown editor (R Studio) to comment out.

Extra yaml blocks can be used anywhere inside the document, and commented out with #

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

No comment.

---
# here's a comment
# ```{r}
# x = pi
# ```
---

Note however that this does not prevent knitr from evaluating inline r code.

I think you should be able to use regular html comments:

<!-- regular html comment -->

Does this work for you?
