Statistical analysis reports with embedded R code, reproducible data science documents, academic papers, and R-based interactive dashboards.
What should I review after converting XUL to R Markdown?
After conversion, review these destination checks: Open converted output in RStudio and verify behavior on real samples; Compare output against the expected depends quality profile; Its strongest workflow assumptions are rooted in the R ecosystem.
