Little late, but here's my plot for this week's #tidytuesday data about British literary prizes. Both shortlists and awardees are getting more diverse, but not in the same way... You can find my code here: github.com/josefinabern...

#rstats #dataviz #rladies #tidyverse #ggplot2

This is a great way to contribute to the #rstats and #TidyTuesday communities!

I'll be running a free, online workshop at @rinpharma.bsky.social on Nov 3rd!

If you've never built an #RStats package before, or if you want to learn some tips to make better packages, come along to build a package together! 📦

🐥 Early-bird announcement

The abstract deadline for BGA 2026 will be February 15, 2026. BGA will take place June 23-26, in beautiful Amsterdam. Time to start thinking about the cool findings you want to share with your international colleagues at our annual meeting!

My first time joining #tidytuesday was a lot of fun! Here is the figure I have created showing different types of meteorological measurements across the UK. Thanks to the @metoffice.gov.uk for the data!

Code is available here: github.com/josefinabern...

classic Winnie the Pooh picture, with Pooj and Piglet walking in the woods. Text: "Pooh?" said Piglet. "Yes, Piglet?" said Pooh. "27,417 parameters," said Piglet. "Oh, bother," said Pooh.

When I made this slide, 27k parameters seemed like a lot

The Association Between Frequency of Social Media Use, Wellbeing, and Depressive Symptoms: Disentangling Genetic and Environmental Factors - Behavior Genetics Meta-analyses report small to moderate effect sizes or inconsistent associations (usually around r = -0.10) between wellbeing (WB) and social media use (SMU) and between anxious-depressive symptoms (ADS) and SMU (also around r = 0.10). This study employs the classical twin design, utilizing data from 6492 individuals from the Netherlands Twin Register, including 3369 MZ twins (893 complete twin pairs, 1583 incomplete twin pairs) and 3123 DZ twins (445 complete, 2233 incomplete) to provide insights into the sources of overlap between WB/ADS and SMU. Both hedonic and eudaimonic WB scales were used. SMU was measured by (1) the time spent on different social media platforms (SMUt), (2) the frequency of posting on social media (SMUf), and (3) the number of social media accounts individuals have (SMUn). Our results confirmed the low phenotypic correlations between WB and SMU (between r = -0.09 and 0.04) as well as between ADS and SMU (between r = 0.07 and 0.10). For SMU, heritability estimates between 32 and 72% were obtained. The small but significant phenotypic correlations between WB/ADS and the SMU phenotypes were mainly determined by genetic factors (in the range of 80-90%). For WB and SMU, genetic correlations were between -0.10 and -0.0, and for ADS and SMU genetic correlations were between 0.10 and 0.23. Genetic correlations implied limited but statistically significant sets of genes that affect WB/ADS and SMU levels. Overall, the results indicate that there is evidence that the small associations between WB/ADS and SMU are partly driven by overlapping genetic influences. We encourage researchers and experts to consider more personalized approaches when considering the association between WB and SMU, as well as understanding the reasons for individuals’ observed SMU levels.

New twin study: Social media use is highly heritable - genes explain up to 72% of why we scroll. It’s not just ‘doomscrolling’ that affects mental health: your background matters. Full study: link.springer.com/article/10.1007/s10519-025-10224-2

{tinytable} 0.14.0 for #RStats makes it super easy to draw tables in html, tex, docx, typ, md & png.

There are only a few functions to learn, but don't be fooled! Small 📦s can still be powerful.

Very artsy 🎨 I’d love to see a version with a legend for the color clusters if that’s possible? Or alternatively an example trait for each color!

LISTEN UP, Y'ALL! Do you have a dataset that you could submit to #TidyTuesday? This could be your first foray into contributing to open source! Let's give Jon some runway! I know we can do it.

Could be a subset of public data! Could be your own! I can help!

Promotional graphic for a Posit Data Science Hangout featuring Jenny Bryan, Sr. Software Engineer at Posit. The text reads: “Hanging out with Jenny Bryan, Sr. Software Engineer at Posit. July 31, 12pm ET, pos.it/dsh.” On the right side is a hexagonal photo of Jenny Bryan, who has light gray hair, glasses, and is smiling while wearing a light-colored hoodie. The background is a dark mauve color, and the Posit logo appears in the bottom right corner.

If you attend *ONE* Data Science Hangout this year, make it this week's hangout with JENNY BRYAN. Trust me ✨

Thursday, July 31st at 9AM PT / 12PM ET - a casual conversation with Jenny powered by YOUR questions. Feel free to lurk or hop in the chat. #rstats #databs

New paper by @njudd.com shows that an additional year of education doesn't causally affect telomere length in old age, despite many (theory) accounts arguing otherwise. It's been desk rejected by 13 journals happy to publish small 'positive' telomere studies. Sigh. www.biorxiv.org/content/10.1...

So curious about this! A developer friend recommended DuckDB to me a while ago but I ignored it since I mainly work in R. Can't wait to learn more about this 🦆 #RStats #tidyverse

As you can see by my big smile I had a lot of fun talking about this project and getting some input! Thanks a lot to everyone at APH Personalized Medicine for your support and insightful questions! I am more than grateful I got the opportunity to go abroad for so long early in my PhD 😊

1/13 New preprint out! We developed methods to test a key assumption in family-based genetic studies: that siblings don’t genetically influence each other’s traits. Spoiler: mostly they don’t, but there’s a twist with ADHD ratings at age 3 👶
