问题描述

有没有办法让代码折叠可用于R Markdown文档中的单个块，而不能用于其他块(不带

Is there a way to have code folding available for individual chunks in an R Markdown document, but not others (without writing customized JavaScript)?

我知道我可以使用code_folding YAML选项，但这适用于整个文档.我想为单个块而不是所有块启用它.

I know I can use the code_folding YAML option, but that applies to the whole document. I'd like to enable it for individual chunks, but not all chunks.

推荐答案

在rmarkdown 1.15之后

这已实现(请参阅相关的问题，

After rmarkdown 1.15

This has been implemented (see related issue, PR and NEWS.md). However you should note that this folds only the code and not the output. You need to add some extra config to hide the code by default and not evaluate it.

在JSFiddle上尝试编织的HTML

此问题已于2019年7月在GitHub上关闭.使用html details 元素的解决方法.com/rstudio/rmarkdown/issues/664#issuecomment-422353592建议rel =" nofollow noreferrer> .

The issue was closed on july 2019 on GitHub. A workaround using the details element in html was suggested.

在实际使用之前，这可以在某些用例中起作用.

This can work for some use cases until it is actually implemented.
