How to keep R code inside page in R markdown output?

I am trying to run the following code in R markdown only to print the code. I do not want to print the results from R code. Some of the lines in code are really large. When I run, it worked perfectly, but some of the lines go outside of the page? Here is the R markdown code

title: R code
output: 
  pdf_document:
    toc: true
    number_sections: true
documentclass: article
classoption: 
  - portrait
  - a4paper

Here is the output R markdown output

I would like to keep all the codes inside the page. Is there any way I do it for all chunk?

r-markdown word-wrap r

I think you're looking for width.cutoff:

You can change your chunk options at the top:

library(formatR)
```{r, tidy=TRUE, tidy.opts=list(width.cutoff=60), eval = FALSE, echo = TRUE}
user_129679380

add ``` to the end of the document, for some reason I couldn't get them to display. Different document format, but you only need to print to PDF from a browser
