🦮 Attention dog owners! One of my trainees is examining the relationship between dogs and toys, and their owner’s thoughts about that relationship. Want to help?   If you have a few minutes, you can complete the survey here: queensu.qualtrics.com/jfe/form/SV_...

Last week, the Nebraska R User Group hosted a presentation by Matt Waite (@mattwaite.bsky.social) on "Talking to LLMs through R". Check out a summary of the talk at neb-rug.github.io/posts/talkin.... #rstats #llms

🚨 The "penguins" data is coming to the base #rstats{datasets} in 4.5.0! @ellakaye.co.uk & @HeathrTurnr.fosstodon.org.ap.brid.gy r prepared an adapted and a raw version of the data set based on the {palmerpenguins} 📦 by @allisonhorst.bsky.social @apreshill.com and Kristen Gorman. 📈 Scatter plot:

🌈 rainbowR meet-up: Wednesday February 26th, 5pm UTC 🌈 - connect with other LGBTQ+ people who code in #RStats 🏳️‍🌈 - ask questions about R 🙋 - tell us about an R package you like 📦 - show us something R-related you’ve been working on 💻 ➡️ Registration via rainbowr.org/meetups

If you're a comparative psychologist and/or a behavioral neuroscientist, and/or if you're interested in learning about those fields, now is a great time to follow @apadivision6.bsky.social! As current president of the division, I can say we've got some fun social media things planned! 🧪💜🦍🐟🐕🦆🦎🐝🐁🐖🦇

Canine perspective taking: Anticipating the behavior of an unseen human. www.cell.com/iscience/ful... New paper w/ L.Huber, P.van der Wolf, M.Menkveld & S.Riemer providing evidence that dogs prefer to steal from a plate unseen by a human when the human's presence has to be inferred from sound cues.

I just got one heck of a welcome home. Volume up, but not too high. The wolves were singing tonight. A few seconds in you’ll hear the closest howling wolf I’ve ever heard. I couldn’t see it, but it might have been at the end of my driveway. I went right back inside after this. 😊🐺🦊

Thanks to everyone's feedback, we have updated our calculator to optimize sample size N & scan time T for fMRI studies: leonoqr.github.io/ORSP_Calcula... The first new feature is that users can explore how different N & T leads to different accuracy, e.g., N=1000 & T=30min => 81% max accuracy. 🧵

Fed up with Meta? Avoiding Instagram or Facebook isn’t enough to stop Meta from harvesting and profiting from your private information. Here’s how to limit Meta’s ability to monetize your personal data.

Clever study that explores the debate between those who claim that color categories are 'innate' and those who argue that they are dependent on language. It turns out that monkeys, unlike humans, do not have consensus color categories, suggesting cognitive mechanisms such as language are required.🧪🧠

The tidymodels group has an #rstats summer internship position this year. The focus is on feature selection tools. All of the information is in the blog post below. We look forward to seeing your applications! www.tidyverse.org/blog/2025/01...

Dropping my lab's @unlcchil.bsky.social 2024 Wrapped! 🥳🎉 Find out how many dogs enrolled in our database, how many participated in our studies, what our most common dog names and breeds were, and lots of other cool facts about our year! #dogs #wrapped

My first article for the year! And timely, given the frigid weather. If you hear loud booms, they might be due to a frost quake. ❄️ @snexplores.bsky.social www.snexplores.org/article/scie...

One could say that Berlin is a city perpetually at war with itself, its identity, its grasp of history, its language. And once a year, this spritual war manifests in the streets. Ancient Chinese weapons, from a more civilized age, are deployed. The goal is only chaos. www.youtube.com/watch?v=16sR...

Interested in upping your ggplot2 game? Check out a blog post on Dr. Heike Hofmann's talk "Extensions to ggplot2 are easy – right?" neb-rug.github.io/posts/ggplot... This was the inaugural talk for the new Nebraska R User Group. Register for future talks at www.meetup.com/neb-rug/ #RStats #DataViz

This is important! It's Especially hard in professional settings like conferences. People want to talk about the dog instead of relating to me as a professional.
