Posit's curated Claude Skills collection — R, data-science, Quarto, and workflow skills from the people behind RStudio and Shiny.

Posit Skills is the skill pack from Posit (RStudio/Shiny). It's biased toward R and data-science workflows but covers Quarto authoring, package development, and reproducible analysis patterns. Higher quality bar than most community collections because Posit ships it as a vendor-maintained catalog.

Usos do mundo real: skills

How to scaffold a proper R package

👤 R developers starting a new package and wanting usethis/devtools conventions ⏱ ~30 min intermediate

Quando usar: You're tired of hand-writing DESCRIPTION, NAMESPACE, and roxygen2 boilerplate.

Fluxo
  1. Scaffold
    Use Posit R-package skill. Create a new package 'tidylaundry' with 2 exported functions: wash() and fold().✓ Copiado
    → Directory with DESCRIPTION, NAMESPACE, R/, tests/testthat/, README
  2. Add roxygen
    Add roxygen2 docs with @param, @return, @examples for each function.✓ Copiado
    → Inline docs that devtools::document() converts to man/
  3. Smoke test
    Write testthat tests covering happy path + one edge case each.✓ Copiado
    → Tests passing under devtools::test()

Resultado: A package that passes R CMD check on day one.

Armadilhas
  • Generated code uses base R where tidyverse would be clearer (or vice versa) — State the style preference upfront

Author a reproducible Quarto report

👤 Analysts publishing reports with code + narrative ⏱ ~45 min intermediate

Quando usar: You need to share analysis with stakeholders in a reproducible format.

Fluxo
  1. Scaffold Quarto doc
    Use Posit Quarto skill. Create a report template with YAML header, exec defaults, and Tufte theme.✓ Copiado
    → .qmd file with chunked code + narrative
  2. Fill with analysis
    Load data/sales.csv and produce a monthly revenue chart with ggplot + a 2-paragraph insight.✓ Copiado
    → Chunks that render to HTML/PDF
  3. Pin environment
    Capture versions with renv::snapshot().✓ Copiado
    → renv.lock produced

Resultado: A reproducible report anyone can re-render given the data.

Armadilhas
  • Quarto render fails silently on missing system deps — Check quarto check output; common issue is missing tinytex or chromium for PDF

Scaffold a Shiny app with modern patterns

👤 R developers building internal apps ⏱ ~40 min intermediate

Quando usar: New Shiny app, want modules + bslib theming from the start.

Fluxo
  1. Scaffold
    Use Posit Shiny skill. Create an app with bslib::page_fluid, 2 modules: upload + plot.✓ Copiado
    → app.R with module files in R/
  2. Add reactive flow
    Wire upload module's reactive output into plot module's input.✓ Copiado
    → Reactives connected; app runs

Resultado: A modular Shiny app that's easy to extend.

Solução de problemas

Erros comuns e correções

Generated R code uses outdated tidyverse APIs

State target package versions: 'dplyr 1.1+, tidyselect 1.2+'

Skill not triggered on R contexts

Claude auto-triggers on file extensions; explicitly invoke 'Use Posit R skills ...' to guarantee
