R markdown: force a character string into more than 1 lines-CodePudding

I have

---
title: "test"
output: pdf_document
---

Below should be in four lines

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
test<-c("This should be in the first line \n This in the second line \n This in the third line \n This in the fourth line")
```
    
`r test`

in the PDF test is displayed in 1 line. Is it possible to knit the test string into 4 lines within Rmarkdown or do I have to preprocess it in R? \n does not seem to do the job.

CodePudding user response：

You need escaping acrobatics, use \\\n.
