dplyr 1.2.0 was released last week and since I use {dplyr} a lot in my work, I wanted to take some time to try some of the new functions.
This post provides some supplemental examples of the new functions, beyond what is provided in the new Posit materials.

average person picks 3 on sliders factoid actualy just statistical error. average person picks 0 on sliders. Sliders Georg, who has a monitor resolutiob over 16,000 x 10,000 aspect ratio, is an outlier adn should not have been counted

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!

Whenever Microsoft Word or some other software tries to finish my sentences for me now, even if that WAS what I was gonna say, I rewrite it now partially out of spite, but also because it's a good way to know that I was going to be overly predictable and basic in my writing

Teaching my personality students a little bit about factor analysis (to a very non-stats audience, in a non-stats class), and in a group assignment a humanities student described items loading on two factors as being "balkanized into two groups" which I kind of love linguistically

Instead of having an hdmi cable to connect a computer to share your screen, the room was set up to ONLY go through microsoft Teams. So, you had to:
a) Sign into a video chat Teams room
b) Then share your screen to the audience through Teams

For any non-Canadian researchers out there, our government recently pumped a ton of cash to try and attract international researchers to Canada. So if you're looking for a change, timing could be good!

a) A floating-point error making a number slightly different across different computers
b) An Rstudio update that briefly killed the glm() function
c) A #stats consult that was a perfect example of Simpson's paradox

The modern world feels like every agency and department is cutting costs, and tries to reduce workload by downloading the work onto their users instead of employees (e.g., an AI chatbot).
In doing so, ALL work takes longer to do because users are less efficient than specialized employees.
