Here's the article I promised about how I built an interactive Plotly.js + R (webR) + PHP + Livewire chart gallery.

I was inspired by seeing some cool Vue and React examples, but this might be the first one with Laravel/Blade.

These are really cool! Gives me some ideas. Thanks for sharing!

I find it really funny how quickly the media and UNC alumni have turned against Bill Belichick. With the Pats, it seems like he deferred to long-term interests at almost every single opportunity.

Hiring him was never going to be a quick fix!

Life would probably be easier if I closed editor tabs in PHPStorm and RStudio when I'm done with them lol

A while back, I had an idea for a fitness tracking app w/ LLM features to help create exercise plans. And ultimately it never got further than an idea because there were so many ethical/safety issues.

Of course, OpenAI is like "just ask ChatGPT, what could go wrong?"

"Hey ChatGPT, please help me tear a pec"

This ChatGPT ad on YT is clearly promoting it as a fitness/health tool. Yuck.

So far I really like ggplot2 4.0.0 a lot, but the color blending with ink/paper means you can end up with too little contrast in your axis text.

Luckily, you can easily detect this with {colorspace} to prevent accessibility issues. see blog for more info

ggplot2 4.0 Ink and Paper: Don’t Forget about Axis Text Contrast — Alex Kraieski

ggplot2 4.0.0 has introduced some very useful improvements to themes, but there's at least one color blending and accessibility pitfall you'll want to avoid.

If you have state-level data and you want to add columsn for US Census regions or divisions, you can use {tigris} to build a lookup table and join it in #rstats (gist here gist.github.com/andrewheiss/...)

library(tidyverse)

# Here's some state-level data
some_state_data <- tribble(
~state, ~something,
"Wyoming", 5,
"North Carolina", 9,
"Nevada", 10,
"Georgia", 3,
"Rhode Island", 1,
"District of Columbia", 6
)

# Neat, but it would be nice to know what divisons/regions these are in!
some_state_data
#> # A tibble: 6 × 2
#> state something
#> <chr> <dbl>
#> 1 Wyoming 5
#> 2 North Carolina 9
#> 3 Nevada 10
#> 4 Georgia 3
#> 5 Rhode Island 1
#> 6 District of Columbia 6

$# Build a lookup table with {tigris} library(tigris) regions_info <- regions() |> sf::st_drop_geometry() |> select(REGION_ID = GEOID, REGION = NAME) divisions_info <- divisions() |> sf::st_drop_geometry() |> select(DIVISION_ID = GEOID, DIVISION = NAME) states_info <- states(cb = FALSE) |> sf::st_drop_geometry() |> select(REGION_ID = REGION, DIVISION_ID = DIVISION, STATEFP, STUSPS, NAME) state_details <- states_info |> left_join(regions_info, by = join_by(REGION_ID)) |> left_join(divisions_info, by = join_by(DIVISION_ID)) |> select( state = NAME, state_abb = STUSPS, state_fips = STATEFP, state_region = REGION, state_division = DIVISION ) |> as_tibble()$

# Complete details!

Does SCOTUS have any credibility left?

Alex Kraieski @alexkraieski.bsky.social · 12d

This is so absurd! So Congress doesn't have the power of the purse anymore?

I guess the constitution doesn't really apply anymore. And it never fully protected us from a hostile judiciary, evidently. Lol

I found a cool API to try out for a hobby project. So I hit it and get a 200 back.

That's the wrong paradigm, though. Reality is I'm trying different shredding parameters

Alex Kraieski @alexkraieski.bsky.social · 27d

What do you mean there's no logging?

No backups of the pickup_heights table?

What do you mean you weren't using git?

This would be catastrophic data destruction at my day job haha

I'm kinda kicking myself for messing with reproducibility by turning a screw I didn't mean to on my guitar, but I guess I kinda learned that guitars are bayesian. We are constantly updating our beliefs about the sweet spot.

Hopefully I didn't fuck up the posterior distribution of this guitar!

This is a paper I really care about. I feel the core message is very important for social scientists in general, and political scientists in particular.

"Quantitative Research in Political Science is Greatly Underpowered."

Is there still journalism out there worth paying for? Seems like paywalls for news are more prevalent than ever, but most of these outlets are way too friendly to incumbents and the powerful!
