Latest version of Positron can open xlsx files in the data viewer(!) and it has a dropdown menu now for previewing different formats of #QuartoPub documents And—most importantly, but also from a few weeks ago, so less new—the plots panel can pick up dimensions from chunk options!!!! #rstats

'The real threat is a slow, comfortable drift toward not understanding what you're doing. Not a dramatic collapse. Just a generation of researchers who can produce results but can't produce understanding' What a nice post on AI, education, learning, research and academia

ABSTRACT

Spreadsheets are widely used software tools for data entry, storage, analysis, and visualization. Focusing on the data entry and storage aspects, this article offers practical recommendations for organizing spreadsheet data to reduce errors and ease later analyses. The basic principles are: be consistent, write dates like YYYY-MM-DD, do not leave any cells empty, put just one thing in a cell, organize the data as a single rectangle (with subjects as rows and variables as columns, and with a single header row), create a data dictionary, do not include calculations in the raw data files, do not use font color or highlighting as data, choose good names for things, make backups, use data validation to avoid data entry errors, and save the data in plain text files.

Hey #rstats teachers: Do you teach RStudio or Positron? I'm prepping a workshop and unsure what to use. I've always taught RStudio but switched to Positron myself. Positron has many advantages but RStudio may be less overwhelming to beginners. What's your teaching experience? Pros/Cons for either?

dplyr 1.2.0 is out now and we are SO excited! - `filter_out()` for dropping rows - `recode_values()`, `replace_values()`, and `replace_when()` that join `case_when()` as a complete family of recoding/replacing tools These are huge quality of life wins for #rstats! tidyverse.org/blog/2026/02...

dplyr 1.2.0
dplyr 1.2.0 fills in some important gaps in dplyr's API: we've added a new complement to `filter()` focused on dropping rows, and we've expanded the `case_when()` family with three new recoding and re...

You can join my free online lecture on GitHub Copilot (Thu 18.12., 4-5 pm CET) I’ll show context-aware code completion, chatting with your scripts and projects & responsible use. I'll use R/Python + Positron; but works similarly in other languages/editors. 👉 Details & link: tinyurl.com/2xubc787

🎄 ANNOUNCEMENT: R Package Development Advent Calendar 2025! 🎄 Starting December 1st, I'm launching a 25-day journey through modern R package development. here's why you should follow along 🧵 #rstats #RPackageAdvent2025 #OpenSource
A festive digital illustration features the blue R logo wearing a red Santa hat with white trim on the left. To its right stands a green Christmas tree made entirely of curly braces arranged in a triangular shape. White and light-blue %>% pipe symbols float across a dark blue, starry background like snowflakes. A speech bubble above the R logo says “Ho Ho Ho! 📦” in red text. At the bottom, white text reads: “R Package Development Advent Calendar 2025” and below it, “25 Days of Coding Magic • Dec 1–25.”
