[英]knitr to PDF not wrapping comments
When trying to knit my Rmarkdown files to PDF, knitr
doesn't seem to wrap the comments and the text just goes outside of the pdf margins.当尝试将我的 Rmarkdown 文件编织为 PDF 时,
knitr
似乎没有包装评论,并且文本只是超出了 pdf 的边距。
I have tried specifying several parameters but nothing seems to have any effect.我尝试指定几个参数,但似乎没有任何效果。

title: "Demo margin"
output: pdf_document

```{r setup, include=FALSE}
options(width=80)
knitr::opts_chunk$set(echo = TRUE,out.width = 40, tidy=T, tidy.opts=list(width.cutoff=60))
```
## R Markdown
This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see <http://rmarkdown.rstudio.com>.
When you click the **Knit** button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:
```{r cars, out.width=80, tidy = 'formatR', tidy.opts = list(blank = FALSE, width.cutoff = 60)}
summary(cars)
#very very very very very very very very very very very very very very very very very very very very very very very very incredibly very long comment
```
## Including Plots
You can also embed plots, for example:
```{r pressure, echo=FALSE}
plot(pressure)
```

How can I get knitr

I had the same problem and even with exhaustive searching found no other solution than either:我遇到了同样的问题,即使经过详尽的搜索,也没有找到其他解决方案:
This issue was fixed after installing R v4.0.0 and reinstalling packages.安装 R v4.0.0 并重新安装软件包后,此问题已得到修复。
