Rmarkdown and escape characters

Question

How can I print the sequence \\$ in R, as it is? I am working in RStudio, bookdown, inside a kable table in an R chunk. I tried four backslashes before the $ or five backslashes before the $ but did not work.

Answer 1

In order to print \\$, you can set escape = TRUE.

One .Rmd simple file as an example:

---
title: "Example with escape = TRUE"
author: bttomio
output: pdf_document
---

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```

```{r kable}
library(kableExtra)
df <- data.frame("Example" = c("\\\\$"))
kbl(df, escape = TRUE)
```

Output:
