The following features are added to formatR.
- Removing more trailing whitespace.
- Adding spaces around more operators of your choice.
Installation
In R, run
> install.packages("RFormatter")
Usage
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("/"))

Command-Line Utility
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")
