#RStats

@tommytang.bsky.social have you tried opencode? Shouldn t we try to prefer the open source variant? And if you connect it with sonnet/opus I found it very powerful.

#rstats I'm glad to announce Jarl 0.5.0!

Jarl is a very fast R linter, written in Rust. This release brings many improvements and fixes.

See the blog post: www.etiennebacher.com/posts/2026-0...

And the full changelog: jarl.etiennebacher.com/changelog

🧵 to highlight some features below

(1/4)

Most statistical tests you learned separately are the same thing.

t-test, ANOVA, Mann-Whitney, Chi-square, Wilcoxon... all just special cases of linear models. y = b0 + b1*x covers almost everything.

Boris Cherny created Claude Code.

Then he open-sourced his entire setup for using it. Memory files, subagents, skills, the whole thing.

Here's what's inside and why you should steal it:

A Few Claude Skills for R Users – R Works The community has come together to create some great Claude Skills that you can try out today.

I rounded up a few Claude Skills for #RStats users.

Huge thanks to the creators who developed them. They share Skills for everything from tidyverse code to brand.yml files to learning while using AI.

Hope the list is useful, and please let me know what I missed! 🧡

@mingemi.bsky.social have you tried opencode with github copilot? if you are a teacher/student you get 300 premium prompts (e.g. claude sonnet 4.6, or 100opus 4.6) for free, which should be similar to claude code (17 or even 100 Dollars). For me that works great although i haven't tried cc yet

#RStats📦rix 0.17.4 is out!

Major #Python QoL improvements: automatic LD_LIBRARY_PATH setup for easy integration with uv, new py_src_dir for editable-style Python dev in #Nix shells, and smarter cachix detection (no more noise on #NixOS).

Plus docs cleanup & cache setup updates

2/2 Using BH/Bonferroni often leaves proteomics (Olink) results underpowered in my analysis, even when scRNA-seq produces plenty of DEGs.
Findings (my interpretation): qvalue and permFDP provide higher sensitivity with only a marginal hit to specificity.

I’ve tried to benchmark BH against qvalue and permFDP.

@tommytang.bsky.social I think you should add permFDP pubmed.ncbi.nlm.nih.gov/36693222/ . I found it very useful in my analysis. I recently tried to make the package more robust github.com/mihem/permFD...

@tommytang.bsky.social it works for me on my PC but not on my smartphone.

@tommytang.bsky.social nice. However if I change to R , loading the R environment crashes chatomics-labs.base44.app/TutorialView... SE for other tutorials

Imo this package is a hidden gem. 💎 I’m no statistician, but the logic is solid.

With many variables, I got different results than BH—it seems to find signals that standard corrections miss

@tommytang.bsky.social @brodriguesco.bsky.social what do you think?

Nice video, and wow you build that fast.
We usually write a manuscript with Google Docs, so we can even work in parallel, I can use citation manager in there etc. What advantage does korppi offer?

Depending on your data type, use the right plot to tell the story.
A nice interactive app to determine what plots you need

#rstats Please welcome Jarl, a new R linter.

Jarl is a CLI tool with extensions in VS Code, Positron, and Zed. It can check thousands of lines of R code in milliseconds.

Jarl provides several output formats, a Github Actions workflow, and more.

This gives a fantastic framing of how to think about reproducibility (it's a spectrum) and how to use renv with intention. Highly recommend, even if you're not using renv, to get a better understanding of how to live in peace as R and package versions advance 🕊️ #rstats

A slide titled “Visual Studio Code – October Update [1.106]” with three columns of feature highlights. Agent HQ: Agent Sessions view as mission control for agent tasks, OpenAI Codex integration, built-in planning agent, custom agents and handoffs, inlined terminal panels in chat. Security & Trust: Open sourcing inline suggestions, tool pre- and post-approval, expanded MCP auth support, control MCP server access with custom MCP registries, Linux device policy support. Great coding experience: Copy text from deleted lines in diff editor, VS Code product icon refresh, Terminal IntelliSense GA, compare source control branches and tags.

Announcing Agent HQ in VS Code: a unified agent experience directly in the editor.

R version 4.5.2 "[Not] Part in a Rumble" (source version) has been released. (You can find it in cran.r-project.org/src/base/R-4/, or wait for CRAN to be updated.)

And what's your opinion on vs code with R vs positron? Tried positron a year and missed a few things including copilot and remote ssh, which is now available. But not sure it is as good.
