如何在 Rmarkdown 生成的 pdf 中适合控制台输出？

Question

I am trying to print str(df) in pdf output of rmarkdown. How do I fit the wide output in pdf?

Answer 1

For PDF output is a bit trickier to wrap lines. One option is using the LaTeX package listings . I will use mtcars dataset as example. Your Rmarkdown should enable the package via the Pandoc argument --listings like this:

---
title: "Test"
output:
  pdf_document:
    pandoc_args: --listings
    includes:
      in_header: preamble.tex
---

```{r, echo=FALSE, warning=FALSE, message=FALSE}
options(width = 300)
str(mtcars)
```

In preamble.tex , you set an option of the package in a different file:

\lstset{
  breaklines=true
  basicstyle=\ttfamily
}

This is the output:
