{report} #rstats package version 0.6.2 is now on CRAN!

MANY bug fixes in this version! Including corrected duplicated text outputs and dramatic speed increases for brmsfit models (which used to refit the model entirely every time).

The aim of the report package is to bridge the gap between R’s output and the formatted results contained in your manuscript. This package converts statistical models and data frames into textual repo...

Wrote up a little intervention post/explanation for my class about why using LLMs for trying to learn programming (as first time learners!) is bad and detrimental datavizf25.classes.andrewheiss.com/news/2025-11...
In the first week of class, I had you read an article about how ChatGPT is philosophical “bullshit”, as well as this other post about AI and LLMs in this class. I’ve seen a surprising increase in the amount of ChatGPT-based weekly check-ins and graph interpretations in the exercises. (In the past, I’ve even had students tell me they PDFs of the slides into ChatGPT to generate interesting and confusing things.) Don’t do this! LLMs cannot find three things that you personally found interesting from the readings. LLMs are not you. It’s a huge waste of time for all of us to for me to spend time evaluating and grading output from ChatGPT. I want to read what you think and do, not what a computer invents. NoteMy personal stance on AI and LLMs Many of you have asked about how I think about and use LLMs in my own work (and in the class materials). Please check this short little page where I explain what I do with text, images, code, research, and learning. In short, I do not use LLMs to create any of the materials for this class, and I do not use them to grade or evaluate any of your work. I’ve even had several students submit completely made up stuff for mini projects and final projects. In your final project, your job is to take a dataset, make three different plots with it, and combine the plots into one graphic that tells some sort of story. I’ve (really truly) received projects like this: (a ChatGPT-generated plot of completely made up data from gapminder) At a very quick glance, that looks like a plausible image. But holy crap it falls apart fast, both comically and tragically. Comically because, like, look at the y-axis in the scatterplot; or the x-axis ticks in the population grown chart that are sometimes spaced every 20 years, sometimes every 10 years, and has 1980 there twice; or the weird blobs in the map. Tragically—and most importantly—literally nothing in this image is real and none of the annotations make sense and none of the colors make sense and everything here is completely meaningless and devoid of any information. It’s pure philosophical bullshit—an image “produced without concern for its truth.” That’s what I mean when I say that it’s a forgetful and unreliable resource. Lots of that code is helpful as an illustration of what’s going on. Lots of the explanation is good and fine. But it subtly changed its mind halfway through and didn’t realize it (because it can’t realize it! it’s just a chain of statistically likely text!) Hopefully you can see where this is dangerous for learning. It can often “teach” you wrong, and you can only recognize that if you know stuff already. It’s extra dangerous if you then take that example output, paste it into your exercise, and submit it. I’m not even concerned about the plagiarism aspect of that—code is code and there are only a few ways to write {dplyr} code that will do this, and it’s easy to adapt from real human-based examples online, so I’m less worried about stealing other people’s work here. I’m concerned that it’s not real data. It made up values of 1, 2, 3, and 4 for some countries to illustrate grouping and summarizing. That’s good and normal. None of that is real. Don’t treat it as real.

I'm in the middle of preparing slides for an "Introduction to R" course. Thought I'd use a figure to explain element recycling in vectorized operations.

I'm exited to announce a new resource about making slides with quarto and revealjs. This book is the combination of all the work I have done in this area, reordered and polished up

There isn't a lot of new information yet, but this format allows me to add more easily

Insighful article by @nrennie.bsky.social, still thinking about switching from RStudio to Positron. I'd be happy to have your thoughts about Positron! I'm currently coding mostly in #RStats, but I've been using more #Python lately.

Wow ... I'd never come across this use of with(), which allows combining the pipe and computing a correlation coefficient. Thanks to @mansthulin.bsky.social for explaining this in his fantastic book www.modernstatisticswithr.com!

ggplot + ggiraph in action ⚡

I teamed up with @cedricscherer.com to put together a fun ggiraph talk for useR conf this year. Of course I had to show an example inspired by him!

Stay tuned for behind the scenes how-tos, tricks, and code. Excited to share more info when the talk is live!

{ralger} #rstats package looks like an absolute game changer in the task of web scraping for people with very occasional need in this rather nerdy task 🤩
Instead of drilling manually through cached HTML, one can use intuitively named functions that just do it ✨
