R Code Formatter (Styler / Tidyverse Style)

Format R Code to the Tidyverse Style Instantly

The R Code Formatter applies tidyverse and styler conventions to any R script in your browser. Paste your code and the tool fixes spacing around <- assignment arrows, comparison operators, pipe operators like %>% und |>, indents nested blocks, and flags any line that exceeds your chosen length. Everything runs locally on your device, so your code never leaves the page.

Nutzung

1. Paste your R source code into the input area, or upload a .R file using the file picker.
2. Pick an indent width (2 spaces is the tidyverse default; 4 spaces is also supported).
3. Set a maximum line length so the tool can flag any line that overruns the limit.
4. Toggle whether top-level = assignments should be rewritten to <- (named arguments inside function calls are always left alone).
5. Copy the formatted output or download it as an .R Datei.

Funktionen

• Tidyverse spacing – Inserts a single space on both sides of binary operators, comparison operators, and pipes; keeps $, :: und @ tight.
• Configurable indent width – Choose 2 or 4 spaces for nested blocks, function bodies, and multi-line argument lists.
• Long-line detection – Flags every line that exceeds the configured maximum (defaults to 80 characters).
• Assignment normalisation – Optionally rewrites top-level = assignments to <- without touching named arguments inside function calls.
• Syntax sanity check – Detects unbalanced parentheses, brackets and braces, and unterminated strings.
• Comment and string safety – The tokenizer protects comment text, regular strings, raw strings (r"(...)") and backtick-quoted identifiers from being reformatted.

Häufige Anwendungsfälle

• Cleaning up R scripts inherited from collaborators or generated by older tools.
• Preparing data analysis or Shiny app code for code review.
• Normalising tutorial or blog post code snippets before publishing.
• Spot-checking generated R chunks inside Quarto, R Markdown or Jupyter notebooks.
• Quickly auditing a script for over-long lines before merging.
