The #rstats community has given me so much, and I give back enthusiastically! I love this stuff. It's easy to talk and teach about stuff you love ❤️❤️❤️ But you're right, this community is just the best, most generous group ✨

Ok, that's it. Just a story about how much I love R, how much I miss teaching, my love for stats, and my amazing friend on her PhD journey 😌 I hope you spent your weekend doing things that feel magical, too!! 🪄✨

We've used this in student exercises (using #rstat R) before...
.. embarrassing that Swiss official news casts on the Sechseläuten use this yearly being seemingly serious about its predictive power ... horrifying me every year.

Niall Ferguson: Without Books We Will Be Barbarians It is not the road to serfdom that awaits—but the steep downward slope to the status of a peasant in ancient Egypt, writes Niall Ferguson.

Niall Ferguson: Without Books We Will Be Barbarians www.thefp.com/p/niall-ferg... quiet convincing & frightening. Will we (mankind) "turn around"?

They tried to kill us (a missile hit like three blocks from us),

We survived (but are very tired),

Let's eat (pancakes!)

After a massive Russian missile strike on Kyiv, teens waited 12 hours at the rubble of their friend’s home.

He was found dead.

Three children were killed in the attack.

One friend said simply, “He was good. I want people to know that.”

I’ve long used FiveThirtyEight’s interactive “Hack Your Way To Scientific Glory” to illustrate the idea of p-hacking when I teach statistics. But ABC/Disney killed the site earlier this month :(

So I made my own with #rstats and Observable and #QuartoPub ! stats.andrewheiss.com/hack-your-way/

It’s worth stating this simply: For literally anyone in the US Govt from 1945 to 2025, Signalgate would require an instant resignation—and a criminal investigation. It would be a matter of personal *honor* to resign. The fact Mike Waltz & Pete Hegseth are choosing to fight it out is a terrible omen.

Government spreadsheets sometimes add asterisks next to a few numbers in a large data set. Why worry about that when I can handle it automatically?
x <- c("10.1", "74%", "23*")
as.numeric(x)
[1] 10.1 NA NA
Warning message:
NAs introduced by coercion
readr::parse_number(x)
[1] 10.1 74.0 23.0

I see; never had the need, but more importantly, the question only involved number strings .. hence why should the answer be about something more complicated... ... but never mind.

Sorry.. a "typo" -- as.numeric("0.01") of course

is this just joking around? `as.character("0.01")` works from the base of base R ..

Bar charts comparing NRC sentiment distributions for Bluesky posts discussing Python and RStats. In Python posts, the sentiments fear, trust, and anticipation show the highest scores of about 1.25%. Among RStats posts, the sentiments trust, anticipation, and joy score the highest, at about 2%, 1.7%, and 1.1%.

Thank you, Sharon. I think we just see Christmas/Chanukka/NewYear holiday break effect; such effects happen all the time (differently in different regions of the globe). Shdn't we rather get the number of posts with #rstats *divided by the total number of bsky posts on that day*?

Exactly. If you're teaching, teach something they can use for free at home. Skills are transferrable :) #Rstats
