My Quarto #rstats tip for big/complex papers is to set up R scripts that do data processing/modeling & save plots/outputs as RDS files. The Quarto can then load the RDS file & make any modifications to the ggplot2 object before plotting. This avoids unwieldy long Quarto docs /w complex caching.

9.2% of all citations go to just 0.32% of psychology articles.
To have the most impact, post-publication peer-review should focus on these influential articles with ≥30 citations per year.
@error.reviews will systemically sample from such articles.

The change was adopted by different states at different times, resulting in what appeared to be a gradual rise in maternal mortality.
