Note on using Gemini Pro for paper references: First, it hallucinated on the year and journal, making it up for a preprint paper. Second: it got wrong the order of authorship for a second paper with the same team, repeating the order of the first paper. Folks, review your AI results.

I recently discovered Conventional Comments (conventionalcomments.org) for providing a pseudo-standard set of labels for feedback and just tried it for an article review and it was really helpful to specify issues vs. thoughts vs. suggestions, etc. Hopefully it's helpful for the authors too!

As a previous co-organizer for R-Ladies Seattle, I know how long a little help can go. That’s why I’m so excited that Posit is supporting community conferences and local meetups! Please share this with an organizer who wants to feed folks some pizza while learning about data science tools 🍕

Come join me for a all new slidecrafting workshop! 2 hours of all new content, teaching you to go from zero to hero in quarto slides! It is free and open to anyone, very minimal quarto knowledge required, we are starting with the basics! pos.it/slide-wrkshp #quarto #slidecrafting

Slidecrafting Workshop with Emil Hvitfeldt

This will be a 2-hour workshop (with a short break) led by Emil Hvitfeldt all about making great slides in Quarto! Wed, Aug 12, 2026 12:00 PM EDT

10 colour palettes I reach for in research charts — curated, and most are colourblind-safe. Categorical + sequential: Okabe-Ito, Paul Tol, Tableau 10, viridis, cividis, magma. Skip default tab10 and rainbow/jet. Which do you swear by? Anything I'm missing? #DataViz #ColorPalette #SciComm

TIL that .callout blocks in quarto can be collapsed using {.callout-note collapse="true"}. So useful when you need a long text like an introduction to be included, but you want to avoid excessive scrolling to get to the main data in the report. #quarto #rstats

I love that #rstats introduced me to some social sciences and economics people. The studies I come across by because of this are quite interesting! I would never see any of this in my biomedical sciences bubble.

Science Bluesky is now much better than Science Twitter is… but I still miss peak pre-pandemic Science Twitter.

Katharine Hayhoe@katharinehayhoe.com · 6mo ago

Bluesky is the new science Twitter, new study by @whysharksmatter.bsky.social and Julia Wester concludes! "Results show that for every reported professional benefit that scientists once gained from Twitter, scientists can now gain that benefit more effectively on Bluesky than on Twitter."

This benckmark does not express how better Claude Code is than the other models on top. Apparently, the reasoning of Opus 4.6 being better makes all the difference. (I've tested it for some bioinformatics data analysis in the last hour and the difference is brutal, even Sonnet vs. Gemini-any).

There is a subtle difference in transforming a vector into a file using writeLines() or write.table(col_names = F, row.names=F): the latter allows quotes in the output. It makes a lot of difference for file paths, for example. #rstats

OMG the proportion this post took. This is NOT a hateful post for tidyverse. I love tidyverse! It is only a person pov while doing more stuff with python pandas*. As @nrennie.bsky.social pointed out, polars is more similar to the tidyverse.

It is much easier to understand python code for data science if you know a bit of base R than if you only know tidyverse. #rstats #python

R is not RStudio

R (el lenguaje de código abierto) y RStudio (el IDE de Posit) son cosas distintas, pero en muchos países de habla hispana usamos los términos indistintamente. Escribí sobre este fenómeno lingüistico/cultural, considerando la adopción (o no) de Positron luisdva.github.io/rstats/RRstu... #rstats

Using quarto with python is a whole new experience. It is *not* a simple switch of languages (if you're an R user like me).

We also have a separate programme for the Global South. If your idea is selected, we will bring the event to your region. #BiologistsWorkshops Details: www.biologists.com/workshops/pr...

Wow. ✨

I started making this R package 6 years ago. I finally have it in a state I'm happy with, thanks to Claude Code #Rstats github.com/MattCowgill/...

Is there any buzzfeed-like quiz out there yet to figure out which AI model is the best for you? It would be fun.

{ellmer} 10/10 in stability to extract structured from unstructured data using #gemini API. I used type_object() to set the desired output, and json to set the input. I'm still experimenting with LLM API calls, but so far it was much better error-wise than a python script with schemas. #rstats

Guys, you need to come up with a better strategy of getting rid of robots. I lose half of my day recognizing buses, bikes and stairs.

Creating a package to organize my work, instead of just reloading functions from scripts, was the best thing I did so far this year. #rstats

3 things I learned from @stephenturner.us workshop on #R pkg development in #Positron - there is a light bulb icon that creates a roxygen template for an R file - available::available("pkgname") checks if the name you want has already been used - {pkgndep} evaluates heaviness of pkg dependencies

I use a gist everytime I need to run a few basic #bioinformatics explorations in a new instance, and thought I could share it here so someone could benefit from it too! I have forked it and adapted a bit to my needs. Here it goes: gist.github.com/flaviaerius/...
