I think, against my better judgement, I’m about to do something I swore I’d never do again β€” submit an #Rstats package to CRAN

I started making this R package 6 years ago. I finally have it in a state I'm happy with, thanks to Claude Code #Rstats github.com/MattCowgill/...

What is the workflow for getting comments and edits from the client? That’s what keeps me and many from going all-Quarto (until {redoc} is revived)

when making a new graph/chart/whatever you really have to ask yourself these two questions imo

1) is this chart/map better than a table
2) is this chart/map better than a bar chart

want to compare two numbers? Bar chart. Add more numbers? Bar chart. Want to add another category of numbers to sit alongside the first? Believe it or not: bar chart.

when did we decide, as a society, that β€œcohort” is just a synonym for β€œgroup” rather than specifically a group that shares some time-invariant characteristic(s)

you’re right, that is self-recommending

It was a post looking for pointers to AI critics and sceptics. I shouldn’t have ended it with a crack at Z*tr*n. I was not looking for a fight, I was looking for links.

I don’t, in fact, want a fight
