@dslc.io welcomes you to week 33 of #TidyTuesday! We're exploring IELTS exam results! 📂 https://tidytues.day/2026/2026-08-18 📰 https://sojourningscholar.com/ielts-score-statistics/ #RStats #PyData #JuliaLang #DataViz #tidyverse #r4ds

TidyTuesday is a weekly social data project. All are welcome to participate! Please remember to share the code used to generate your results!
TidyTuesday is organized by the Data Science Learning Community. Join our Slack for free online help with R and other data-related topics, or to participate in a data-related book club!

How to Participate
Data is posted to social media every Monday morning. Follow the instructions in the new post for how to download the data.
Explore the data, watching out for interesting relationships. We would like to emphasize that you should not draw conclusions about causation in the data.
Create a visualization, a model, a shiny app, or some other piece of data-science-related output, using R or another programming language.
Share your output and the code used to generate it on social media with the #TidyTuesday hashtag.

Plot showing distribution of IELTS scores by native language ordered by median score. German, Marathi, Russian and Afrikaans have a higher median score than English. The distributions are also different. The most frequent score for Germans and Russians is 8, while the most frequent score for English-speakers is 6.

We've previously featured commercial-business-related datasets on #TidyTuesday, (eg promoting a conference). Due to an influx of AI-generated submissions intended to promote products and services, we are no longer accepting submissions promoting commercial businesses, products, or services.

When @jameshwade.bsky.social mentioned hex stickers at our last #PositConf2026 speaker training, I realized I didn't have any for stbl.wrangle.zone, the #RStats 📦 I'm speaking about! Thankfully I had time to order a small batch. The url is unreadable, I'll have to fix that if I order another batch.

@dslc.io welcomes you to week 32 of #TidyTuesday! We're exploring the Palomar Spectroscopic Survey of Nearby Galaxies! 📁 https://tidytues.day/2026/2026-08-11 📰 https://arxiv.org/abs/astro-ph/9704108 #RStats #PyData #JuliaLang #DataViz #tidyverse #r4ds

A scatter plot showing the BPT diagnostic diagram for 408 nearby galaxies observed with the Hale Telescope. The x-axis is the log ratio of nitrogen to hydrogen emission lines and the y-axis is the log ratio of oxygen to hydrogen lines. Points are colored by nuclear activity type: blue for star-forming H II regions clustered at lower left, red for Seyfert nuclei at upper right, orange for LINERs at right, and green for transition objects between the groups.

This week's #TidyTuesday explored Basotho wool. It's the lifeblood and pride of many of Lesotho's people 🐑 The shift from India to China was an interesting one. #Dataviz #Datavis #DataVisualization #RStats #Quarto #ggplot2 #Inkscape #GIMP Repo 🔗 github.com/afrikaniz3d-...

A stacked waffle chart titled "Decoupling, Regional Realignment, Secondary Buyer Re-entry, and Emerging Markets" analyzes Lesotho’s wool trade from 2010 to 2024. Each stacked spool icon represents $500,000 USD, organized into 5-column wide annual towers. Color shades reflect yearly trade volume relative to each nation's historical range (Low, Mid, Peak).

South Africa (blue) dominates early trade alongside India (terracotta). Following the 2018 Agricultural Marketing Regulations and COVID-19 shocks, traditional South African pipelines severed as China (green) rapidly expanded to share market dominance through 2024. Annotations highlight the 2018 regulatory shift away from South African brokerage BKB toward direct Chinese licensing, as well as the 2023 re-entry of India and the inaugural appearance of Uruguay (charcoal) at the $500K threshold.

A legend defines spool tiers across the four nations, and a bottom caption details the fourteen-year structural shift in global Basotho wool demand.

#TidyTuesday week 31 - Basotho Wool #DataViz #Rstats

A woven-textile chart shows reported import values of wool from Lesotho by destination. South Africa received the largest value at $282 million, followed by China at $173 million; India received $12 million and Uruguay $215,000. The differing panel heights use a logarithmic scale.

@dslc.io welcomes you to week 31 of #TidyTuesday! We're exploring Basotho Wool! 📁 https://tidytues.day/2026/2026-08-04 📰 https://groundup.org.za/article/the-mountain-men-behind-lesothos-wool-wealth/ #RStats #PyData #JuliaLang #DataViz #tidyverse #r4ds

A horizontal bar chart titled 'Global Basotho Wool Imports (2023)' displaying the total trade primary value in USD across four importing countries from Lesotho. The countries are listed vertically on the y-axis, ordered from largest value at the top to smallest at the bottom: South Africa ($38M), China ($24M), Uruguay ($215K), and India ($141K). Each country is colored with a unique solid bar, and the exact formatted dollar amounts are labeled in bold next to the right edge of each bar. The x-axis representing total import value is clean with no line or tick marks, letting the data labels communicate the values. A descriptive text caption below notes that the visualization utilizes mirror trade statistics based on UN Comtrade primary value reporting.

Max kuhn@topepo.bsky.social · 3w ago

We're happy to announce our new #rstats package: lorax. If you fit tree-based models, lorax enables conversion to the party package's format (for making nice tree diagrams) and has methods to compute which features were used, the number of terminal nodes, etc. opensource.posit.co/blog/2026-07...

#RStats 📦 {stbl} 0.4.0 is updated on CRAN! Biggest changes: the backend is rewritten in C, and there's a C API if you'd like to do stbl-like checks at a lower level in your packages. Please let me know if you give it a try! I'll speak about stbl & function design at #PositConf2026 in September!

@dslc.io welcomes you to week 29 of #TidyTuesday! We're exploring Near-Death Experiences (NDERF)! 📂 https://tidytues.day/2026/2026-07-21 📰 https://nderf.org/ #RStats #PyData #JuliaLang #DataViz #tidyverse #r4ds

A dumbbell chart titled 'Changed Forever' comparing life changes 8 years after cardiac arrest between NDE experiencers (purple dots) and controls who did not have an NDE (gray dots). NDE experiencers show dramatically higher rates of becoming more loving/empathetic (73% vs 41%), decreased fear of death (47% vs 16%), and increased belief in afterlife (42% vs 16%).

And so after a very brief hiatus, version 0.7.0 of "learning statistics with R" exists. Full rebuild in quarto, stylistic fixes, "epilogues from 2026" to comment on how the world changed since original publication, and as an added bonus, no longer misgenders the author learningstatisticswithr.com
