是否可以在 R Markdown/knitr 中创建伪代码的代码块?

Is it possible to create a code block of pseudocode in R Markdown/knitr?

我试过使用反引号和波浪号,但它们需要语言。我只想要一个带高亮背景的格式化纯文本代码块。

使用 eval=FALSEtidy=FALSE 直到到达关键字 if,后续代码将在 .Rmd 文件和输出 PDF 中以颜色突出显示.不通过选项指定语言会删除背景突出显示输出中代码的功能。

```{r, eval=FALSE,tidy=FALSE}
loop through each species
    loop through each measurement of the current species
         if measurement ...
etc.
```

使用 tidy = FALSE

```{r, tidy=FALSE, eval=FALSE, highlight=FALSE }

pseudocode

```

编辑:添加高光,以防统一颜色

这里有一些示例代码可以很好地呈现 HTML。它还可以正确呈现为 Word 和 PDF。

title: "Untitled"
output: html_document

Here is some plain text.

Next, let's write some pseudo code.  Note that you don't _have_ to specify a language if using plain backticks.

```
object <- [some kind of calculation]
```

If you set `eval = FALSE` you can get the highlighted background

```{r, eval = FALSE}
object <- [some kind of calculation]
Note that this; is not valid R code
```

You may find it interesting that your example works just fine for me.

```{r, eval=FALSE}
loop through each species
    loop through each measurement of the current species
    ...
etc.
```
