Hive mind, please help me out! I need a more informative and explicit subtitle for my upcoming #RStats book "Model to Meaning" The premise is that analysts should often transform coefficient estimates into more meaningful / interpretable quantities like predictions, risk differences, slopes, etc.

I’ve long used FiveThirtyEight’s interactive “Hack Your Way To Scientific Glory” to illustrate the idea of p-hacking when I teach statistics. But ABC/Disney killed the site earlier this month :( So I made my own with #rstats and Observable and #QuartoPub ! stats.andrewheiss.com/hack-your-way/

Excited to announce my hands-on & in person workshop: "Introduction to 3D maps and data visualisation with Blender". You will learn how to create memorable 3D visualisations that stand out. #dataviz Register here: lu.ma/gtg2elht

I've been working on a history of the tidyverse for an upcoming special issue of the Australia/New Zealand Journal of Statistics celebrating 25 years of R. I'd love to get your feedback! What have I missed? hadley.github.io/25-tidyverse... #rstats

The data at USAID's ForeignAssistance dot gov was removed over the weekend, but it seems to be back (for now). As a backup, I've uploaded the data both as static CSV files and a queryable API - Details: andrewheiss.github.io/foreignassis... - API: foreignassistance-data.andrewheiss.com

A reminder that {modelsummary}, {tinytable}, and {marginaleffects} are Canadian so if you're an American researcher, you'll have to increase your citations of those #rstats packages by 25%, err, next month.

You know what I haven't done in almost 900 days? A livestream! Join me on YouTube on January 31st at 2pm Central (UTC - 6), where I'll walk through / break down some monochrome maps I made for a forthcoming book. (And I'll try to remember how live streaming works). youtube.com/live/KK5rayw...

How do autocrats stay in power? Our new research dives into the strategies of political control—repression, co-optation, and indoctrination—used across 229 autocracies from 1946 to 2010. What we found will change the way you think about authoritarian resilience. 🧵👇

Hi I'm Helen and I don't know how Bluesky works! I'll be sharing maps & dataviz that I make and love - as well as tutorials on how to recreate them! These will likely be interspersed with photos of my enormous cat and/or lunch.

Salty dude from ESRI uses popularity to judge the utility of tools. Also fails my freshman methods course with what he thinks science is (hint: it ain't because you use hard objects like pipettes and calipers). Half-baked trolling attempt; 1.5 out of 5.

#rstats and #QuartoPub PSA: @vincentab.bsky.social's {tinytable} is the absolute best table making package out there for LaTeX output (it natively supports tabularray!), and it's phenomenal for HTML. It has fully replaced {gt} and {kableExtra} for me vincentarelbundock.github.io/tinytable/

Killington Ski Resort. #rayshader adventures, an #rstats tale

I genuinely do not understand what this is like but it sounds rough. Not having to deal with this is a perk of an utter nobody like myself. He gets ~20 emails an hour; I get less than that a week, almost all of which are campus announcements and the like.

I have now also ported the color vision deficiency simulation app to Shiny live. Advantage is this runs entirely in your browser, even though you "upload" the image it never leaves your computer.

Okay, this is it for the evening. Will keep working on it but I need to think of something else to do to keep myself motivated. Here's Jiminy Peak Resort, Hancock, Massachusetts. Thoughts/suggestions welcome! #rayshader adventures, an #rstats tale

Apparently the area around Breckenridge has over 9 million trees. Killington? 6 million. Time it will take to render them? Days. Path traced? No chance since the 300,000 trees I've been working on all day consumes 80GB of memory. Where's the result? None. It's been failure after failure today

Any {lidR} experts know how to remove artifacts from data? I have huge random spikes I can't seem to remove. Would normalize_height work? #rstats #geospatial

Some years ago I wrote a simple R app to explore colors in HCL space. While it's clunky, it still is my preferred way of selecting colors, because it offers features other color selectors don't normally have. Today, thanks to shinylive, the app is available standalone. 🧵

Trying something different. #rayshader adventures, an #rstats tale

Update: Skiing was a blast! ⛷️ I think I'm hooked. Didn't fall once except when I tried to parallel turn, forgot everything I was supposed to do, and promptly fell over. Then realised I didn't know how to get up without removing my skis. 😅 Kid didn't like it unfortunately. But we will try again.

Bee-nado, meet sharknado! :P 🦈 #rayvertex adventures, an #rstats tale

Just a regular reminder: the ArcticDEM is one of the most beautiful spatial datasets out there. I've been working on a large tile set for our #arctic abrupt thaw mapping activities recently and I can't help but stop and take a peek as the data rolls in.

Just amazing how Tyler keeps making the rayverse better year after year! Thank you! 😊😊 Also, this is my present 🥳🥳

Presenting…The Cartographer’s Nook: A Miniature! #miniature #mappycraft #GISChat

Am going to learn to ski as an older adult with my 5yo. A little nervous I'd get injured. The last time I snowboarded, I hurt my coccyx so badly it hurt for three months. tbh, I'd rather be 30m underwater but we are supposed to do winter stuff in winter, she said. Any tips?

These are stunning.

1/3 Denoising: Absolute game-changer for pathtracing/3D #Dataviz! The below is being rendered in realtime (!) with #rayrender in #RStats. I was worried for a while about CRAN portability (this requires an install of OIDN), but my configure-fu has gotten good enough that I can work around that now.

A belated #30DayMapChallenge 2024 round-up. 30 days, 28 visualisations. First time in four years I missed not one, but two. For some reason, it was a pretty rough month. Still mostly the #rayverse and #rstats where possible.

I taught some probabilistic programming yesterday, specifically the eternal battle against the demons of floating point arithmetic. I have an old (2023) 15 minute bonus lecture online on the topic, for those who fancy battling monsters. Link to video (starts at 1h mark): youtu.be/mt9WKbQJrI4?...

Some time ago, I created an #RStats pckg to reproduce J. Bertin's valued point maps Today, here's an application of this package, replacing the dots with silhouettes from @albertocairo.bsky.social 's WeePeople font.

I’ve had many interesting conversations about the election & what the next Trump administration will bring. Is the US set to slide into authoritarianism? Will we wall ourselves off from the world? Is it a new dawn of American prosperity? Might Trump remake the whole political landscape? 🧵 1/N

#30DayMapChallenge · Day 27 · Micromapping. Almost there...this is Lombard Street, San Francisco. #rayshader adventures, an #rstats tale

#30DayMapChallenge · Day 26 · Map projections. Another one. New Zealand often gets left out of maps. In fact, the code I used to turn the global forest cover map into circles left out NZ! I felt bad so here's a forest cover map of NZ. #rayshader adventures, an #rstats tale

#30DayMapChallenge · Day 26 · Map projections. Thought this was a new idea but had a nagging suspicion I saw it before. And indeed I have! It was created by the amazing @pokateo.bsky.social. Here's my attempt: Ten ways to draw Greenland. #rayshader adventures, an #rstats tale
