Important post on the "cooptation of science reform by anti-science actors"

Jeff Lockhart@jwlockhart.bsky.social · 5d ago

I wrote about science funding, science reform, and anti-science agendas. scatter.wordpress.com/2026/07/31/s...

#rstats My take: rownames(df) was the original mechanism for labeling obs. All base R knew this, so plot(lm(y~x, data=df)) did the right thing (outliers, influence plot) for obs. deserving to be noticed. tidyverse changed that, perhaps rightly so, but the auto-labeling aspect was largely lost.

Mid terms are November 3rd 2026. Go register voters.@usrbinr.bsky.social · 5d ago

so anyone use the rownames attribute often in #rstats? curious if there are any advantages or conveniences that this attribute brings?

A recent post on the `gt` #rstats package helped me tweak the handling of multi-column stubs in color_table() in the {vcdExtra} package. Only on friendly.r-universe.dev for now. Before After

Strong claim here: "Ordinal models are virtually as efficient as parametric ones even when parametric model assumptions are met" What's not to like?: "In a CPM there are as many intercepts as there are distinct y-values, less one. " This deserves some serious study 👍

Should we start to worry about DAG-hacking?

Peter Tennant@pwgtennant.bsky.social · 2w ago

Drawing principled DAGs is a fundamental part of the observational research process. It is nonsensical for funders to expect to see the 'final DAG' or the 'final list of confounders' before a research project has been funded. By all means ask about the DAG design process. But not the final DAG!
