format_R_source_code: Formats R source code.

In RFormatter: R Source Code Formatter

Description

format_R_source_code is very much based on formatR, but tries to improve it by heuristics. For example, spaces can be forced around the division operator /.

Usage

format_R_source_code(source, formatR_arguments = list(),
  remove_trailing_whitespace = TRUE, spaced_operators = c("/", "%%",
  "%/%", ":", "^"))

Arguments

source	String with source code to format. This not the filename of the source file.
formatR_arguments	List of arguments passed to formatR via its tidy_source.
remove_trailing_whitespace	Boolean: should horizontal whitespace at the end of lines be removed?
spaced_operators	Vector of strings with operators around which spaces are forced.

Value

String with formatted source code.
