R Markdown Knitr 转 PDF 代码外边距 [英] R Markdown Knitr to PDF Code Outside Margin

问题描述

我想在文档末尾附上我的全部代码块.代码包括绘图、插入图形、计算等.它的长.这是在我运行了相应章节中的相关代码之后.在这一点上，我不希望代码生成任何结果，而只是简单地显示代码，以便其他人可以检查我所做的事情.

I want to attach the entirety of my code chunks at the end of my document. The code includes plots, inserted graphics, calculations and so forth. It's long. This is after I have run the relevant code in its respective chapters. At this point, I don't want the code to generate any results, but simply show the code so that others can check on what I have done.

这是部分代码的示例:

shapefile1 <- readOGR("./Folder1/Folder2/Folder3", layer = "TM_WORLD_BORDERS-0.3") # Read in world shapefile

当我编译时，它显示在我在 YAML 标头中为我的文档设置的边距之外

When I compile, it shows up outside the margin that I have set for my document in the YAML header like this

geometry: top=2.5cm, bottom=2cm, left=3cm, right=3.5cm

我尝试了以下解决方案:

I have tried the following solutions:

选项 1:

在 RStudio 的 R markdown 中，如何防止源代码跑出 pdf 页面?

```{r, eval=FALSE, tidy=TRUE, tidy.opts=list(width.cutoff=60)}
```

选项 2:

```{r, eval=FALSE, out.width=".9\\paperwidth"}
```

都不适合我.我唯一能想到的另一件事是手动缩短代码行，但我确信这不是最好的选择.这是怎么做的?

Neither works for me. The only other thing I can think of is manually making the code lines shorter, but I'm sure that can't be the best option. How is this done?

推荐答案

当我在 R Studio 中使用pdflatex"作为 Latex 引擎时会发生这种情况.当我更改为xelatex"时，这种情况不再发生.但是在降价开始时我也需要这个代码块:

This happens to me when I use "pdflatex" as the Latex Engine in R Studio. When I change to "xelatex", this doesn't happen anymore. But I also need this code chunk in the beggining of the markdown:

library(knitr)
# Set so that long lines in R will be wrapped:
opts_chunk$set(tidy.opts=list(width.cutoff=40),tidy=TRUE)
