Look how huge it is! It's almost too heavy to hold, even when it's empty 😅

I have two mugs that are almost too huge to use, and they're both magnificent. This one makes my heart glow & is full of coffee. I guess it's vintage now! Or special edition? #rstats #databs #RStudio

(The other one is a Steven Universe mug covered in all the characters! It's almost a soup bowl 😂)

new #dplyr filtering function who dis 😍 meet filter_out()!

👍 GO PUT A THUMBS UP ON DAVIS'S TIDYUP THINGY ON GITHUB TO SHARE MY ENTHUSIASMMMM!! #rstats #databs

And, you know, provide your thoughts on this newly-proposed function if you have them 😌

Custom #Positron title thingy of "file - project - branch" is now miiiiine!!

YAAAAS

You know how in #RStudio, it puts your branch name at the top? Like "project_name - branch - RStudio" (shown here)

I want that in #Positron 🤔 and I haven't found a popular extension for it. (I think there is one that works in VSCode, but not in Positron!)

Any ideas, #rstats #databs crew?

I got some questions about how I use my chess timer, and a video is just easier, so here you go!

Also, it's been nice to see the overlap between my #ADHD crowd and my #databs crowd. I keep using the #ADHData hashtag to include both, and I hope others will use it, too!

She thock 😌

My #ADHD brain doesn't feel time, so I capture it with a chess clock.

Player 1 on the left is "off the clock" & Player 2 on the right is "on the clock" - clearly my cat stickers are resting/playing vs business mode 🥹

Caveat: this only helps if I actually remember to press the buttons 😭 #ADHData

I also shared how the "when" clause of keybindings works, like in my custom keybinding here (enters a new line and a hash symbol) that is only for R and only for use in the Editor pane:

I had SO MUCH FUN making the data science trivia game for positconf Virtual Day this yr, & all I've wanted since then is to do it again! But it was a big lift to make it happen. What if I did daily trivia instead? I could do it as a poll on the data science community discord! #databs #python #rstats

This summer, I sat down with my friend Saumita & give her an intro to ggplot2. She's a capable pythonista, so I skipped the fluff & just showed what plotting with #ggplot2 in #rstats can look like.

If you're in a similarly Just Curious re: ggplot2, lemme know!

Happy Halloween!! I do a complex pumpkin every year, but my energy levels were so low this time, I went as simple as possible, and I freaking love my happy pumpkin bud 🥹🥹🥹

I definitely contemplated an #rstats pumpkin, but my brain is a fried egg today. I used pumpkinstenciler.com to build my own!
November 1, 2025 at 4:28 AM
Dude, have you pulled up the keybindings and just searched a few? THERE ARE SO MANY. Why?! How do they not all overlap?! These are all the shift+enter commands, with my custom key binding highlighted. I decided I didn't mind it overlapping most stuff, and hopefully my when clause is specific enough

The solution, using scales = "free_y", space = "free" inside facet_grid, incorporated into my reprex, in case anyone cares 😆

When you type out your mental code block and then IMMEDIATELY remember how to fix your own problem, because talking/typing things out and creating a reprex works. #databs #rstats #ggplot2

It's past midnight but you're a family of night owls and there's WEATHER happening, so the family group chat is wide awake.

TOMORROW! Join me on the #DSHangout with @tanho.ca to chat all about... whatever you want! Great topics: R in Production, sports analytics, open source dev work, and pumpkin carving 🎃 ❤️

I plan on asking about my fave: working out loud!

So classy 😤

Fun Libby fact: I LOVE PENS & PENCILS & PAPER! Just refilling my favorite ink pen in about 1 minute with almost no mess ✨✨✨ This is the Tom's Studio Lumos in the Lilac dual-tip body with a 0.3 writing nib. Doing this almost one-handed to film it was not ideal, usually it's faster 😂

I don't really have favorites (I contain multitudes), and until i saw @christophmolnar.bsky.social ask this funny question, I don't think I'd realized how enamored I am of SVMs. They're just so beautiful, especially radial SVM.

Also on my list of loves: KNN!

Here's a screen grab of the docs (I can't link to the section in the pdf, which stinks) It says, median is the time at which the Kaplan–Meier survival function S^(t) first drops to 0.5, like by this time, 50% of pop is est to have experienced the event. So I asked what your KM curve looked like :)

All the community-focused stuff is pretty spot-on, but it makes it look like my life is work. At least it depicted a couple eating together, so not ALL work, but goodness the geometrically improbably copy of Intro te gapiot2: no Pythui(n?)sted is bizarre 😂 I guess it knows I regularly teach ggplot2

I don't do trends, & I VERY RARELY use AI to generate images, bc AI images make me feel queasy & I'm an illustrator myself, so 👀. BUT. I got curious w/ this trend of asking GPT what my life looks like. I'm worried I've given it too much context about me 😩 Is my life all @posit.co, #databs, #rstats ?

🍰 Happy 15th anniversary to us 🥂

AND THEN I got nerdsniped so good & ended up in LaTeX-land bc my buddy was trying to get a header image on each page of a #quarto PDF 😂

Anyway, here's how I did it. #LaTeX isn't my thing! Don't judge. Should this be a blog or is it boring? Helpful? #rstats #databs
