It’s been a lot of fun working on this project and connecting marketing methodology with my political science roots.

An introduction to Python for R users – Occasional Divergences This introduction to Python assumes you know R, which is used as an analogy to explain Python for data analysis.

There are a lot of introductions to Python, but this one is mine. It includes a walkthrough of using uv for environment management, Polars for data wrangling, seaborn.objects for visualization, and scikit-learn for modeling. #rstats #python #pydata

Headed back home after a whirlwind visit! Logan is a gorgeous city and USU is doing really neat work with teaching data analytics

PyData Northern Utah is partnering with HackUSU for a special in-person meetup: An introduction to Python dashboards using polars, seaborn.objects, and Quarto: www.meetup.com/pydata-north...

For our first PyData Northern Utah meetup of 2025, we are continuing to look at a data wrangling tools with @healthandstats.bsky.social as guide. For anyone in and around Cache Valley, join our Northern Utah chapter at www.meetup.com/pydata-north...

Python ignorance validated. I didn't realize there was a kernel selection option inside the Jupyter notebook. Thanks for the assist, @juliasilge.com.

This may be Python ignorance on my part, but I'm wondering if there is something under the hood that makes Positron not play well with Jupyter notebooks? @coatless.bsky.social have you seen anything like this?

Data Wrangling with Polars, Wed, Nov 20, 2024, 6:00 PM | Meetup Join our first PyData Northern Utah meetup to learn about data wrangling with Polars. This will be a hands-on workshop, so come prepared to learn and ask questions. We will

For anyone in and around Utah State University, come join a new chapter of PyData and learn about data wrangling with Polars next week! #python #databs

This administrative attack on the nonprofit sector fits with a pattern of authoritarian restrictions on civil society that's been going on for the past decade+ @suparnac.bsky.social and I (and others) have done a bunch of research on this from an intl/comparative perspective #nonprofitsky #polisky 🧵

YouTube video by Julia Silge First look at Positron, exploring orca encounters

My first screencast in quite a while! Take a first look at how to use #Positron, the new data science IDE I have been working on, for data analysis with #rstats, using this week's #TidyTuesday dataset on orca encounters 🐳

We've got a brand new, baby website for Positron! Take a look if you are interested in getting started, and please let us know how it goes:

Four scatterplots showing the same relationship four four datasets, all showing a slope of 1, but in reality they all have different true slopes that can only be uncovered through proper statistical adjustment

Four common DAGs: a collider, a confounder, a mediator, and M-bias

Just discovered the Causal Quartet by @lucystats.bsky.social, @travisgerke.bsky.social, and @malcolmbarrett.malco.io: four datasets that have the same unadjusted casaul relationship between treatment/outcome but different true effects. This is great for teaching DAG-based causal inference! #rstats

Okay, I’ll bite: How do you read so much?!

George Stagg just released a new #quarto extension that allows for an embedded full feature code editor inside of Quarto slide deck! It supports both #rstats via #webr and #python via #pyodide.

Fun with Positron | Andrew Heiss Combine the best of RStudio and Visual Studio Code in Posit’s new Positron IDE

New blog post! Read about Posit's new Positron editor, see some of the neat new features it has, and check out the settings and extensions I use. It includes a bonus workaround for connecting to a remote server with SSH! #rstats

A screenshot showing the Positron IDE GitHub Release page with new tag updates since it was just released.

#positron IDE beta has been updated since last week! Two nice changes:

1. Quarto Extension (not the CLI) is now bundled; and,
2. Prelim support for #polars in data explorer

A full list of changes can be viewed using GitHub's compare url with tags.

Yeah, this was my whole reason for writing that blog post. It's simple, but just me trying to grok all this as an RStudio user.

Sure thing! It's not much, but hopefully it's helpful.

Coding in R and Python with Positron – Occasional Divergences Positron is a “next-generation data science IDE.” If RStudio is too specific and VS Code is too general, is Positron just right?

Curious about Positron, @posit.co's new IDE? I try and summarize how it appears to bring together the best of RStudio and VS Code. #rstats #pydata #positron occasionaldivergences.com/posts/positr...
