What's new in R 4.6.0? Here we summarise some of the more interesting changes in the April 2026 release of R 4.6.0.

New blog post about R4.6 #rstats

I've just reproduced your example (for 24.04). It took a minute to install tidyverse - which is nice! I'm assuming it's slower due to pinging r2u.stat.illinois - are there UK/EU mirrors?

Claude Code's Entire Source Code Was Just Leaked via npm Source Maps — Here's What's Inside A security researcher found Anthropic's full CLI source code exposed through a source map file. 1,900 files. 512,000+ lines. Everything.

If you use GitHub (especially if you pay for it!!) consider doing this *immediately*

Settings -> Privacy -> Disallow GitHub to train their models on your code.

GitHub opted *everyone* into training. No matter if you pay for the service (like I do). WTH

It's not going ahead this year.

Last chance for the early bird discount to AIP in Production. We've started adding speakers as well.

I feel quite old. I can't even be bothered explaining to everyone why they should use "=" instead of "->" in #rstats anymore.

We changed our R user group to "Data Science" a few years ago. It just meant that half the talks were R, half were Python, and 4 times as many people attended!

It wouldn't be that to hard to cancel any group with no events for the last 2 years and ping any group with no events for the last year

I've done this far too many times!

The Reith Lectures - Jonathan Sumption - Law and the Decline of Politics - Rights and the Ideal Constitution - BBC Sounds Jonathan Sumption assess the pros and cons of written and unwritten constitutions.

Related. I was listening to www.bbc.co.uk/sounds/play/... a few days ago. Consistution vs rule of parliament

Okay, this is quite outstanding from Bedford Council.

So just now I'm sitting at 600. That includes work (Uni and @jumpingrivers.com), personal and 2 kids (the latter adds a lot).

The other week kids started a club. That involved an account for the club and the national body. So 4 straight away! Spotify. 5 accounts (sonos + individual).

Agreed. I did a pruge of passwords in my password manager. I had been using it for 12+ years and had over 800+ accounts. Ok a large number were trying a service and never going back. I even had Olympics 2012 login details

Workshops suitable for those who are just starting with #Ai to the seasoned experts

Keeping things consistent. When I open projects it feels that the panes are all different widths, heights, etc

Does this screenshot help?

Thanks. I was thinking more about the variables pane being minimized on start up

In #Positron, is there a way to set the default sizes of panes, and if they are open at startup.

Thoughts: It was quite a fun process. It allowed me to iterate through a few ideas before settling on one. It obtained the population data on its own.

Cons: I'll check the final code, but I never check the intermediate code. Does this mean I might miss something?

A cartographic visualization titled "Africa's Linguistic Diversity" showing the number of languages per million people across African nations. The map employs a monochromatic blue color scheme ranging from pale ice blue (#e0f4ff) for countries with fewer languages per capita to deep midnight blue (#0a1128) for those with the highest linguistic diversity, all set against a black background. The three most linguistically diverse countries are labeled on the left side with their national flag emojis and connected to their geographic locations via white lines: the Republic of the Congo (🇨🇬) at the top with 12.8 languages per million people (shown in the deepest blue), Botswana (🇧🇼) in the middle at 6.0, and Namibia (🇳🇦) at the bottom with 8.1 languages per million (both shown in medium-dark blue). The geographic pattern reveals that Central and Southern African nations, particularly smaller population countries, maintain higher linguistic diversity per capita. Most West African countries appear in medium to light blue tones, indicating moderate diversity. North African countries are rendered in dark gray, signifying missing data in this dataset which focuses on sub-Saharan languages. A legend on the right shows

#TidyTuesday Used the data to create a linguistic heat map - scaled by Population size.
This graph was created purely using #ai (in this case @posit.co databot). It

I just had to buy a new underfloor heating box. The app had disappeared from the app store when I upgraded my phone.

Replacement is app free!
