I'm a huge fan of {targets} and the interactive web browser created by tar_watch() is simply a joy to use. #rstats

Can anyone recommend some data science podcasts on really any aspect of the biz? My go-tos are the R podcast and the test set, but curious what others are listening to! #rstats #pydata

Looks like some awesome talks. Can't wait to dig in!

New feature in the Positron Notebook Editor: Inline data-explorer view. Whenever you print a pandas or polars dataframe you get an inline interactive view powered by Positron's data explorer. This allows you to view and sort massive dataframes.

Positron users - do you set up multiple (all?) projects in a single workspace or open up each project into its own workspace. I'm thinking the latter is more common but I'm curious to know if others use the multiple-projects-in-one-workspace approach. #positron #rstats

Working on Shiny apps for the passed few weeks, boy am I glad the browser() function exists. It makes it so much easier to walk through reactives as they're being evaluated. Check it out if you've ever felt stuck working on a massive Shiny app! #rstats #rshiny

I'm new to the world of neural networks and am 8 years late to this video, but this video really helped me build intuition for what happens under the hood. Thanks @3blue1brown.com! youtu.be/aircAruvnKk #rstats #pydata #machinelearning #deeplearning

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! tidyverse.org/blog/2026/02...

Come learn about deep learning with us! The Data Science Learning Community just started reading the free third edition of Deep Learning with Python. Meetings are Tuesday at 3 pm CST. DSLC: dslc.io Book: deeplearningwithpython.io #rstats #pydata

For this week's #tidytuesday I looked at the sentiment of classic Christmas novels and found the most 'joyous' ones on the basis of a sentiment analysis. If you want extra joy next holiday season, Angel Unaware may be a good read! #dataviz #rstats #ggplot2

Hey folks! I built a Canadian trade database to practice what I'm learning about DuckDB. The database includes all Canadian imports and exports from 1988 to present as per Statistics Canada. Here's a blog post I wrote with more details: joshpersi.github.io/blog/posts/0... #rstats #duckdb

I'm taking my very first crack at OJS for this week's #tidytuesday! It's a super basic plot but getting going with OJS was a challenge, so I'm calling it a win! #DataViz #RStats #ggplot2

Who knew Florida had so many roundabouts? For this week's #tidytuesday I struggled to match each interval's colour intensity with the midpoint of the interval. I couldn't figure it out in code and ended up pulling from coolors.co/gradient-pal... #DataViz #RStats #ggplot2 #tidytuesday

I took this week's #TidyTuesday as an opportunity to try and brush up on modelling and learn tidymodels.org. I have no great modelling insights to share, but in making this graph, I did learn you can set line-ends to be round in geom_line(). Who knew?! #DataViz #RStats #ggplot2

testthat 3.3.0 is here! Major updates for #RStats testing include failure messages for easier debugging, 6 new specific expectations, and the SlowReporter to find your bottlenecks. Heads Up: R 4.1+ is now required, and old mocking functions are removed. Read the post: tidyverse.org/blog/2025/11...

The Data Science Learning Community is starting a new book club cohort for DuckDB in Action this Wednesday. Come read and learn with us! All are welcome! DSLC: dslc.io DuckDB in Action: motherduck.com/duckdb-book-... #RStats #python #DataScience #OpenSource

A very long time in the making but I'm eager to share I've made a Quarto blog to talk about all the data science stuff I'm learning! First post is about adding data source and author attributions in ggplot2! Feel free to stop by! joshpersi.github.io/blog #RStats #Quarto #DataScience #OpenSource

This is my first time joining in on the #TidyTuesday fun. Looking forward to seeing what everyone else is doing with this week's data! #DataViz #RStats #ggplot2

10 minutes is all we were allowed for day 13 of the #30DayMapChallenge. This took me about 15 minutes, so I'm a little over, but this was a fun way to work under a time constraint and avoid endless tweaking! #DataViz #RStats #ggplot2

Day 11 is all about minimalism so I made a map with four lines! Perhaps too minimal, but I also couldn't find geographic data on the stations themselves, so maybe it was meant to be 🤷 #30DayMapChallenge #DataViz #RStats #ggplot2

It's day 10 of the #30DayMapChallenge and the prompt is 'air', so I plotted global air temperature! #DataViz #RStats #ggplot2

Day 8 of the #30DayMapChallenge and I'm plotting a road network of Montréal! #DataViz #RStats #ggplot2

For the "accessibility" prompt on day 7 of the #30DayMapChallenge, I decided to investigate how accessible the default #ggplot2 colours are to people with different types of colour vision deficiency (and for different numbers of colours used). 🎨 #RStats #DataViz

I learned how little I know about accessibility with day 7 of the #30DayMapChallenge. I tried to use a legible font and added an alt-text, but my colors are low-contrast and I have no idea how far off of best practice I am. If you have resources on making maps accessible, please share them with me!

Day 6 of the #30DayMapChallenge makes things 3D! I took my elevation map from yesterday and made it so with the {rayshader} package. #DataViz #RStats #ggplot2

The prompt for day 5 of the #30DayMapChallenge was 'Earth' so I tried to plot the elevation of the Kananaskis Valley!

For Day 3 of the #30DayMapChallenge, I mapped the regions and departments of mainland France! I learned a lot about {ggrepel} but couldn't quite get the labels to be on the outside of each region. Something to work on for next time!

Day 2 of the #30DayMapChallenge is all about lines. Here's a single line that's near and dear to my heart — the Pacific Crest Trail!

Already a couple days behind! Here's my contribution for the first day of the #30DayMapChallenge. The HMS Terror and Erebus were abandoned during John Franklin's attempt to find the Northwest Passage. #DataViz #RStats #ggplot2
