If there an option to execute the code, show the R source code, but hide all kinds of output?

Currently, I use the method of reusing code chunk:

```{r chunk1, include=FALSE}
print('Hello Yihui')
```

```{r chunk1, eval=FALSE}
```

Hello,

I'm sorry if this is the wrong place to ask, but is there a way to exclude whole sections of a R Markdown document from being knitted to a Word document? I mean the text outside of the chunks included in that section, too.

I've tried to find an answer but all the results I get are only about chunks, and not the text of the rest of the document.

Thanks in advance.

This is a really good question, but currently the answer is not straightforward. This is something I intend to work on in future: rstudio/rmarkdown#974 Before that, you have to use HTML comments and set knitr::opts_chunk$set(eval = FALSE) in the comments.

Thank you very much for your quick response. I really hope this option gets implemented in the future, because it'd be incredibly useful for those cases when you are continually updating a statistical report and want to conserve the oldest parts but not saving them to the final document.

Thank you again for your contributions to R.

The asis engine is really helpful here. See this discussion: ropensci/unconf18#74

I think it will be helpful to include it in the cheatsheet, but I guess our cheatsheets are not maintained through Github. You need to reach out to Garrett: https://www.rstudio.com/resources/cheatsheets/how-to-contribute-a-cheatsheet/ Thanks!
