The R Formatter formats R source code. It is very much based on formatR, but tries to improve it by heuristics. For example, spaces can be forced around the division operator "/".

The R Formatter formats R source code. It is very much based on formatR, but tries to improve it by heuristics. For example, spaces can be forced around the division operator `/`

.

The following features are added to formatR.

- Removing more trailing whitespace.
- Adding spaces around more operators of your choice.

In R, run

Try

```
> RFormatter::format_R_source_code("if (b) { f() }")
> RFormatter::format_R_source_code("p = 2", list(arrow = TRUE))
> RFormatter::format_R_source_code("(k/n)^x", spaced_operators = c("/"))
```

To format a source file `source.R`

via a command-line interface, do the following. **Warning: the original file is overwritten, so better back it up first! Use this at your own risk.** Run

```
$ Rscript [utility] source.R
```

where `[utility]`

is the path given by

```
> system.file("exec", "utility.R", package = "RFormatter")
```

Have a look at Yihui Xie’s formatR.

- Multiple operators with overlapping operands are now properly spaced (#1).
