R Formatter
Format and beautify R code with tidyverse style and consistent indentation
R Formatting Tips
- Use <- for assignment instead of = to follow R conventions.
- Keep lines under 80 characters for better readability and diff comparison.
- Use consistent spacing around operators: x + y, not x+y.

Frequently Asked Questions
Common questions about R Formatter formatting answered
Yes, our R formatter is completely free with no registration required. All processing happens in your browser.
Yes, our formatter follows the tidyverse style guide with 2-space indentation, proper spacing around operators, and consistent pipe formatting.
Yes, the formatter properly handles both magrittr pipe (%>%) and native R pipe (|>) chains with consistent alignment.
No. The formatter only adjusts whitespace and indentation. It never modifies identifiers, functions, or data operations.
Yes, the formatter handles ggplot2 layered grammar with proper indentation for each geom, stat, and theme layer.
The tidyverse style guide (which styler, the R community's reference formatter, implements): 2-space indent, <- for assignment (never =, which has different semantics in function arguments), snake_case naming, and no semicolons. The Google R style guide converged to the same core choices in 2020.
Both the native pipe |> (R 4.1+) and magrittr %>% break one verb per line, indented two spaces, with the pipe operator ending each line. This is the most-changed construct in R formatting: unbroken pipes are the top readability complaint in R code review.
<- and = differ: inside a call, mean(x = 1:5) names an argument while mean(x <- 1:5) assigns into the enclosing scope AND names the argument. The formatter normalizes top-level assignment to <- (statistically standard) but never rewrites = inside calls, where doing so would silently change scoping.
