Can I use this for progress bars in R scripts?

Yes, the skill provides patterns for cli_progress_bar() and cli_progress_step(), which handle automatic cleanup and customizable formatting.

How does this skill improve R error handling?

It replaces basic stop() calls with cli_abort(), which allows for bulleted context, inline markup for variables, and significantly better error design patterns.

What is inline markup in the cli package?

Inline markup is a specialized syntax (e.g., {.fn function_name}) that allows the cli package to automatically apply consistent styling to different types of R objects in the console.

Is this compatible with base R output?

While it replaces base R messaging, it is designed to integrate seamlessly with the R ecosystem, including rlang, glue, and testthat.

Does it support complex pluralization?

Absolutely. It includes a robust engine for handling singular, plural, and zero-case text based on the numeric value of variables provided in the string.

Styles and structures R console output using semantic messaging, progress indicators, and professional terminal formatting.

概要

The r-lib/cli skill enables Claude to implement sophisticated, user-friendly command-line interfaces for R packages and scripts. It provides a comprehensive framework for semantic messaging—including formatted errors, warnings, and alerts—alongside dynamic progress bars and complex pluralization logic. By leveraging inline markup and theme-based styling, this skill helps developers transform raw console output into structured, accessible, and visually professional terminal experiences that follow modern R programming best practices.
