Day 10 of #AdventOfCode, base R - part 1 only. Since we are dealing with on/off, we can treat each position as a bit. Convert button values and the target state into integers, and use the magic of bitwXor() to flip bits until the target is reached. Code on GitHub: github.com/ataustin/adv... #RStats

{livelink} walked so {webrarian} could run. Mini browser-based #rstats environments powered by #webR and its 4-panel editor. YAML config, build, preview. Done. R package coming soon. #pyodide folks, stay tuned.

Day 9 of #AdventOfCode, base R! Part 2 was tailor-made for all the data nerds (🙋‍♂️) who prefer to understand their problems through visualization. I'm sure the problem could be solved without a plot, but it definitely reduced the possibility space! Code on GitHub: github.com/ataustin/adv... #RStats

Day 8 of #AdventOfCode, base R! I have to believe parts 1 and 2 can both be done with hclust() and cutree(). But I'm missing something obvious in part 1, so it's just some inefficient loops for now. At any rate, I ❤️ R's built-in data tricks. Code on GitHub: github.com/ataustin/adv... #RStats

Fondly remembering my early #RStats days when I spent an hour trying to identify the NAs in a vector before I knew about is.na()

I was a couple months into my data analysis for my masters thesis when a friend of mine discovered and pointed out Stata's missing value quirks. It could have been an ugly defense if I hadn't fixed that

LinkedIn delivering serious insights with its version of Wrapped. Well done, thought leaders everywhere

I reject the premise of the question

My dad still talks about how easy it was to work on cars when he was young. Nowadays you have to know how to decompile the binary

Maybe I don't understand business, but if you have to rely on your retired founder to come in to get your strategy back on track (or to watch models train), what does that say about your long-term viability as a company?

WHEW! Day 7 of #AdventOfCode, base R only! Part 2 had me stumped. Shout-out to @karstendick.bsky.social for posting an approach that I could implement, namely "the number of paths through a node is equal to the sum of paths through its parents." #RStats github.com/ataustin/adv...

I ignored the strip.clip argument in #ggplot2 for way too long 😲 Combined with a small negative margin tweak, you can place facet labels inside each panel. A tiny trick that makes small multiples feel so much cleaner. 🔵 no manual coordinates 🔵 inherits theme styling 🔵 scales nicely when resizing

Back in the top 10, baby! Eat your heart out, "#rstats is dying" thinkpieces. 😜 www.tiobe.com/tiobe-index/

apropos of nothing: using R to render a blue sky to post on bluesky #RStats #rayrender

Day 6 of #AdventOfCode, base R only! For part 2, I had the unhinged idea of just rotating the data and stitching it back together. As long as I could identify which elements belonged to which operator, it was the same problem as part 1! Code on GitHub: github.com/ataustin/adv... #RStats

%notin% coming soon to an #rstats environment near you 🤩 developer.r-project.org/blosxom.cgi/...

Day 5 of #AdventOfCode! A very messy, kinda-hacked-together solution. In part 2 I start with the low ranges and move upward, continuously widening them where there is overlap, and repeating. I used comments or I'd never know what happened 😂 Code on GitHub: github.com/ataustin/adv... #RStats

Day 4 of #AdventOfCode! The core idea was to use a binary 0/1 matrix to indicate roll position. To compute neighbor counts, shift the matrix around and keep adding up the values. This extended to part 2; remove rolls and repeat until none can move. Code on GitHub: github.com/ataustin/adv... #RStats

Hot dog, looks like I have to submit a travel budget proposal real quick

Day 3 of #AdventOfCode, base R! Took me 3 tries to get a fn that generalized for both parts. The approach is to identify candidate digits and use which.max because it always identifies the first largest. Then adjust candidate window accordingly. Code on GitHub: github.com/ataustin/adv... #RStats

This one struck a nerve with me. So much time spent in quarterly survey results meetings, leaders asking "what are we going to do about these numbers", me saying "we know WHAT people answered but we don't know WHY" and then the meeting just carries on like we can do anything about it

Here's something: I'm constantly sent surveys conducted annually by companies and what puzzles me is that they ask different questions every year. They'll be like 45% of people want to quit their jobs/ are stressed/ whatever. Then we'll ask, is that unusual? What was last year's? They're like 🤷‍♂️

Day 2 of #AdventOfCode, "still sick" edition. Need to rest so just posting part 1 for now. It's a literal interpretation: for integers with even number of digits, split in half and compare. This won't hold up in part 2, so maybe I'll dream the solution 😴 Code: github.com/ataustin/adv... #RStats

Pretty sure this is off by an order of magnitude

Google Photos won't generate my annual recap unless I turn on facial recognition, so I guess I'll go bang rocks together. #googlePixel

When I do trainings on data visualization, I make sure to mention that all the same principles in viz also apply to slides. Use one big message per slide. Don't make me think hard to see it. Keep it simple and sparse. Highlight the key point. Use colors wisely. Clutter is distracting. Etc!

Day 1 of #AdventOfCode! As per tradition I got sick so I'm moving slow. I resisted using an explicit loop in part 2 for some reason, trying out different vectorization options. But the moral is: just do the thing that works! Code on GitHub: github.com/ataustin/adv... #RStats

The unfortunate trajectory of my career has finally forced me to launch* a SageMaker notebook. Is this really an improvement over what we had? *by which I mean: follow a very specific guide to the letter which still results in a failed provisioning

Let the games begin! #AdventOfCode

Language: base R only, per tradition (also it's the only coding I get to do all year) IDE: VS Code because too lazy to set up something new Chair: usually under a blanket on the sofa Sleep: toddler keeps waking me up Water: intense hydration before my nightly AoC cocktail #RStats #AdventOfCode

The first #AdventOfCode 2025 puzzle comes out in about five hours! What's your plan? What language(s?!) are you using? What's your IDE of choice and why is it Vim? Do you have a comfy chair? Did you check out the beta release of Lua 5.5? How much sleep have you gotten? Drinking enough water? 🌟 ❤️ 🎄

@profanity.accountant I don't think I swear much on the socials but maybe you'll prove me wrong

Tis the season! Friendly annual reminder about my {secretsanta} 📦 for running your group's surprise gifting event. I didn't get a chance to test it out yet this year (Gmail auth changes sometimes) so please report any bugs. github.com/ataustin/sec... #RStats

I brought up an idea during a conversation with the youngs and one of them said "I was just talking to ChatGPT about that!" it's uglier than I thought out there

sick flex

I just learned that a new hire to the org at $DAYJOB got a master's in data science without ever taking a probability or statistics class, and I have SO MANY QUESTIONS #dataBS

A team member just moved to town from the east coast, so of course we baptized her with the Chicago handshake #chicago

Continuing my #python Rgonomics posts for the #rstats crowd, wrote a short post about the different ways to use (non-polars) user-defined functions in a pipe Not the most groundbreaking thing, but one of those "the thing I needed to read a bit ago" posts (1/) www.emilyriederer.com/post/py-rgo-...

Aurora down in northern Illinois. Only the third time I've seen it

This man absolutely understood the assignment

*cracks knuckles* let's go AI fishing

I've been dipping my toes in package development for #lua, #python, and #bash and #rstats friends -- let me tell you I didn't realize how good we have it with {devtools} , {usethis}, and the rich supportive rstats community

remember how in The Matrix, agents were the bad guys? #genAI

I'm in this post and I like it! Check out an overview of a recent Posit webinar in which I join a panel of brilliant insurance analytics professionals to talk about changes in the field. #posit #dataBS #insurance

Wake me up when gen AI can schedule a recurring meeting at a time convenient for both parties and proactively adjust future conflicts.

happy "it's not so bad to be using MS Teams" day to all who celebrate #AWS #outage

People at work have been telling me "live long and prosper" which I know is not a Data thing, but TIL there is a Vulcan salute emoji and how did I not realize this earlier 🖖

Chicago showing off today #chicago
