[英]Is it possible to create a code block of pseudocode in R Markdown/knitr?
I've tried using backticks and tildes, but they require languages. 我尝试过使用反引号和波浪号,但它们需要语言。 I just want a formatted code block of plain text with highlighted background.
我只想要一个带有突出显示背景的纯文本代码块。
Using eval=FALSE
and tidy=FALSE
works until reaching a keyword such as if
, the subsequent code will be color highlighted in both the .Rmd
file and the output PDF. 使用
eval=FALSE
和tidy=FALSE
直到达到关键字(如if
,后续代码将在.Rmd
文件和输出PDF中以颜色突出显示。 Not specifying a language through the options removes the capability of background highlighting the code in the output. 不通过选项指定语言会删除背景突出显示输出中的代码的功能。
```{r, eval=FALSE,tidy=FALSE}
loop through each species
loop through each measurement of the current species
if measurement ...
etc.
```
Here's some sample code that renders to HTML just fine. 这里有一些示例代码可以很好地呈现给HTML。 It also renders correctly to Word and PDF.
它还可以正确呈现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.
```
Use tidy = FALSE 使用tidy = FALSE
```{r, tidy=FALSE, eval=FALSE, highlight=FALSE }
pseudocode
```
edit: Added highlight, just in case you uniform color 编辑:添加突出显示,以防您统一颜色
