NEW Cost of living, calls for change undergird Mamdani lead in NYC Voters call city unaffordable and prioritize someone bringing "needed change" over "right experience" Trump also a factor, with majorities wanting next mayor to oppose him on ICE and National Guard www.cbsnews.com/news/cbs-new...

I’m at #positconf2025! Feel free to send me a message or come up to me to talk anything redistricting, R, or quarto related!

Update: As best as I can tell, this is caused by #rstats ggplot2 breaking binned scales in 4.0.0. ggredist errors because it uses palette::palette() which creates a vctrs vector. If you use a character vector of colors, it doesn't error, but the plot appears to be wrong. github.com/tidyverse/gg...

I've never seen a CRAN email mentioning the update of another #rstats package before: > The new errors are from yesterday's update of {ggplot2}. I guess it makes sense for the scale of revdep checks, as nearly 20% of other packages import ggplot2!

I am beyond excited to announce that ggplot2 4.0.0 has just landed on CRAN. It's not every day we have a new major #ggplot2 release but it is a fitting 18 year birthday present for the package. Get an overview of the release in this blog post and be on the lookout for more in-depth posts #rstats

With the end of #rstats extrafont, is showtext/sysfonts now the best way to use custom fonts with ggplot? Or maybe systemfonts?

One super useful #rstats package: pushoverr (cran.r-project.org/web/packages...) Send push notifications to your phone or computer from R with: `pushover(message = ‘your code is done’)` @pushover.net has a 30 day free trial and then a one time $5 charge for a perpetual license.

Simple and lightweight #rstats package to make this available to other Home Assistant users: github.com/christopherk... Right now, it returns lists. Normally, I tidy these, but this seems wrong for the type of back-and-forth used. Please let me know if you have thoughts!

When running #rstats devtools::check(), are other people seeing: Warning message: In system2("quarto", "-V", stdout = TRUE, env = paste0("TMPDIR=", : running command '"quarto" TMPDIR=C:/... -V' had status 1 (... being a normal path) I'm seeing it on multiple Windows machines, but have Quarto

Please stop spamming #rstats with your bots Use a descriptive tag so we can can choose to follow, and not have to trawl through so much churn I can't see any option other than blocking the accounts, I'm interested in CRAN updates (and others) but gee, it should be about humans and actual ideas

There’s been a lot going on in the redistricting world these days. I want to reiterate one important finding: courts typically follow clear, written rules! christophertkenny.com/drafts/princ... There’s lot of variation, but when rules are explicit, they normally bind in court.

Using #rstats to control the lights in my apartment (ignore the cat-centric furnishings for my cats, Tibble and Coda)

Trump’s proposed rush job Census isn’t just immoral and regressive—it will harm communities across the country and compromise data quality: @chriskenny.bsky.social and I in @thehill.com today: thehill.com/opinion/camp...

Do you use tract boundaries in your research? Jake Brown, @simko.bsky.social, and I have a new working paper (osf.io/preprints/so...): Any Way You Slice It: Racial Segregation Statistics are Robust to Aggregation Bias We show that tract-level segregation is robust to MAUP using simulation methods.

Jasny, Kenny, McCartan, Simko, Wu, Zhao, Arora, Ebowe, O'Sullivan, Samarth, Imai: Gerrymandering and geographic polarization have reduced electoral competition https://arxiv.org/abs/2508.15885 https://arxiv.org/pdf/2508.15885 https://arxiv.org/html/2508.15885

A lot of talk about blue book exams www.nytimes.com/2025/08/26/o... and I'm surprised that they're seen abnormal. Less than a decade ago, I was taking prelim exams writing Java in pencil in blue books. Blue books are effective and were quite standard before covid. No reason not to use them more.

Updated working paper for "Individual and Differential Harm in Redistricting" with @corymccartan.com Provides an better method to evaluate electoral fairness, focused on individuals and explicit counterfactuals. One framework for party, race, ideology, religion, etc. Updated draft: osf.io/nc2x7_v2

Could that be @melodyyhuang.bsky.social's new #rstats package for sensitivity analyses? 👀

Take a look at our new working paper, which separates out changes in gerrymandering and geography to better understand bias in congressional redistricting. US geography is becoming slightly more balanced in terms of House seats, but competition is decreasing, largely due to geographic polarization.

Nice to see our research used in the NYT Upshot! www.nytimes.com/interactive/...

9 days, I guess. Journal submissions still need LaTeX unfortunately...

I was so excited to see these data released that I wrote a short blog post showing how to get started in #RStats: rworks.dev/posts/anes20... Many thanks to @statsteph.bsky.social and Rebecca Powell for their review and feedback💙

A quick comparison of California's legislature's new proposed plan to 5,000 simulated redistricting plans. The arrow shows the change from 2022's commission plan to the new proposal. Aggregating to seats, this adds about 3 new Democratic districts in CA.

Taking inspiration from the ridiculous microbenchmark, made a LLM generate functions for generating actual nested loops functions after feeding it the #RStats language definition,Luke Cherney's codetools and some gratuitous #tailcall for the connaisseurs sounkou-bioinfo.github.io/ridiculousBu...

#Rstats thank you Luke Tierney/R Core 😂 Doing as good as the snake in interpreted loops despite massive corporate investment on that other side and the fundamental issues with R's homoiconic nature Note: CPython 3.14 might be faster, they are getting a jit thanks to Microsoft

Setting up a new work laptop. How long do you think I can make it on just Typst and no LaTeX?

#rstats Retro: This is when I implemented SVG animated textures in ggplot2

new vcr release v2! vcr helps record & replay HTTP interactions in #rstats tests. Major update w/ better defaults, enhanced security, new local scoping tools & improved debugging. Huge thanks to @hadley.nz for the majority of work on this release 📋 github.com/ropensci/vcr... 📚 docs.ropensci.org/vcr

I haven't posted much on it, but I'm a big fan of Typst and built the #rstats `typr` pkg (github.com/christopherk...) to render Typst docs. The R community can gain a lot from using Typst's near-instant rendering for PDF/PNG/SVG file formats. I'm working on some new pkgs using Typst's versatility...

CRAN is updating their cross-package references for #rstats packages. Be sure to check your spam, as this went straight to mine!

Texas was already arguably the biggest Republican gerrymander in the nation, according to this PNAS paper by @chriskenny.bsky.social @corymccartan.com @simko.bsky.social @shirokuriwaki.bsky.social www.pnas.org/doi/abs/10.1...

A classic #rstats pattern: 1. Update a package after a year+ of no updates 2. Get an email the next day that 1 additional check fails 3. Wait to see if anything else fails 4. Receive an impolite admonishment from Ripley for ??? resubmitting the package *when no resubmission occurred*

Sharing two new quarto #quartopub templates for #polisky journals: now: github.com/christopherk... for QJPS, Journal of Historical Political Economy, and other now Publishers journals oup: github.com/christopherk... for PSQ, Publius, Policy and Society, and other Oxford Unity Press journals

If you like NYTimes election maps color schemes, you recreate make them in #rstats with the `palette` packages:

Poking around with `tools::CRAN_authors_db()` introduced in #rstats 4.5.0. An estimated 2,641 packages are maintained by people using university emails. (Don't take this too seriously. It only counts edu email variants and `CRAN_authors_db()` doesn't include all packages.)

Update to the #quartopub projector extension (think beamer but w/ typst): Works with the newest Quarto/Typst versions! Quarto 1.7.22 required updates for Typst >= 0.13.0 New themes at github.com/christopherk... Including: metropolis, friendly, a @mattblackwell.bsky.social esque cousteau, & techy

I love RStudio but the bane of my existence is the (not so, but still relatively) new ProjectId field in Rproj files. Constant clashes in medium collaborative projects in #rstats. So many headaches without any clear benefit. Might mean it’s time to trick my collaborators into only using Positron…

A lawsuit in Rockland County, NY, alleges election irregularities in the 2024 Presidential and Senate races. The plaintiffs claim statistical anomalies and uncounted votes. But do these claims hold up? I analyzed the data and I don't think they do: christophertkenny.com/posts/2025-0...

#rstats package `congress` to study #polisky is updated to account for congress api changes over the last 18 months! Install with `pak::pak(‘christopherkenny/congress’)` to get the current version. I’ll submit to CRAN next week when outstanding questions are concluded and vignettes are added.

The university accepted my dissertation! So here’s my @typst.app + @quarto.org template for Harvard GSAS dissertations, now that I know it meets their formatting standards: github.com/christopherk...

You saw or you made something related to #QuartoPub #Quarto either with #ObservableJS, #RStats, #Python or #JuliaLang? You want it to be seen/shared? Please submit a suggestion issue to #AwesomeQuarto PS: if you like this list, star it and share it 😉 github.com/mcanouil/awe...

A quick little project: `typr`: A package to render #Typst documents from #rstats. It's configured to work out of the box with an installed version of the `typst-cli` or just plain Quarto #quartopub. (You may be asking "why?" and it's simple: this side project helps a different side project...)

I've been playing with using #quartopub to make a #typst Polylux output. Introducing `projector`. Essentially, this provides a beamer-in-quarto syntax for a typst-powered alternative. Try it out at: github.com/christopherk...

A new chapter and a new hat: Excited to share that I'll be joining Princeton DDSS in the fall as a postdoc! Looking forward to working with some great people and advancing the computational social sciences!

I've been playing with Quarto shortcodes, so here's a simple CV template that is easily customized using shortcodes and renders quickly/prettily using Typst: github.com/christopherk...
