Build a reproducible R statistical report

Any 8 GB laptop for ordinary statistical models. Large Bayesian or spatial models may require more RAM and longer compile times.

Lock and render from a clean R session

Rscript -e "if (!requireNamespace('renv', quietly=TRUE)) install.packages('renv'); renv::init(bare=TRUE); renv::snapshot(prompt=FALSE)"
quarto check
quarto render
test -d _output
Rscript -e "renv::status()" > _output/renv-status.txt
sha256sum renv.lock _quarto.yml _output/* > _output/SHA256SUMS

Known pitfalls

• A lockfile records packages, not external system libraries.
• Set random seeds inside analysis code and record simulation settings.
• Quarto freeze can reuse old computed results; clear or refresh intentionally before release.
• PDF rendering also depends on a TeX distribution.

Browser only. Check storage, memory and project-hour limits for the selected hosted plan.

Cloud export manifest

export_before_archive:
  - source_qmd
  - _quarto.yml
  - renv.lock
  - references.bib
  - style.csl
  - data_dictionary.md
  - sessionInfo.txt
  - rendered_html_or_pdf
exclude:
  - credentials
  - raw_restricted_data
  - temporary_cache
rule: Verify the exported project renders outside the hosted workspace.

Known pitfalls

• Hosted compute limits and prices can change.
• Do not place secrets in .Rhistory or report source.
• Export the complete project before account or plan changes.
• Cloud reproducibility still requires a lockfile and external dependency notes.
