Variable name with space inside R Markdown Inline Code

[raniere.silva]

How can I use a variable name with space inside R Markdown inline code?

Minimal Working Example

---
title: "MWE"
author: "Raniere Silva"
date: "08/11/2021"
output: html_document
---

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

```{r}
`foo bar` <- 1
```

'foo bar' is `r `foo bar``.

Use Cases

CSV column name has space on it.

You can do something like this:

---
title: "MWE"
author: "Raniere Silva"
date: "08/11/2021"
output: html_document
---

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```
```{r}
`foo bar` <- 1
```

'foo bar' is `r get("foo bar")`.

This obviously a rich incentive to not use spaces in variable names. If they occur in data files, then they should really be repaired using (for example) janitor::clean_names().
