在 knitr 选项中将行间距调整为 1.5 间距

Question

我想将以下代码调整为 1.5 行距，而不是常规输出的双倍行距：

```{r setup, include=FALSE}
hook_chunk = knitr::knit_hooks$get('chunk')

knitr::knit_hooks$set(chunk = function(x, options) {
  regular_output = hook_chunk(x, options)
  # add latex commands if chunk option singlespacing is TRUE
  if (isTRUE(options$singlespacing)) 
    sprintf("\singlespacing\n %s \n\doublespacing", regular_output)
  else
    regular_output
})

knitr::opts_chunk$set(echo = TRUE, singlespacing = TRUE)
```

代码原为postet

我怎样才能做到这一点？感谢您的帮助！

Answer 1

尝试在 YAML header 中定义 LaTeX 包 setspace 并直接将 \onehalfspacing 设置为 LaTeX 命令。

output: pdf_document
header-includes:
    - \usepackage{setspace}

\onehalfspacing
