Knitr中R降价的全局注释选项 [英] global comment option for R markdown in knitr

问题描述

要更改输出的前导字符，.md中的针织块具有注释选项，例如

To change the leading characters for the output a knitr chunk in .Rmd has a comment option, like

```{r comment = ""}
1:100
```

是否有一种全局设置方式，而不是每个块都单独设置?

Is there a way to set this globally, not separately for every chunk?

opts_knit$set(comment = "")

不起作用，我无法在文档中的任何地方找到它.

does not work and I cannot find it anywhere in the documentation.

推荐答案

使用opts_chunk$set()，因为这是 chunk 选项； opts_knit用于软件包选项(很抱歉，相似的名称似乎使您感到困惑).参见 http://yihui.name/knitr/options

Use opts_chunk$set() because that is a chunk option; opts_knit is for package options (sorry about the similar names which apparently confused you). See http://yihui.name/knitr/options
