Happy to know I'm not the only one who creates a ggplot2 theme package for every company I work with #positconf.
Not only does it standardize communication, but it also makes a great impression. theme_quintoandar() took about a day to make and led to me reporting directly to the C-level.

Been working with ClaudeCode for the past ~2 months (mainly R and Quarto). My main tips:
1. Plan a lot.
2. Manually approve (auto-accept only for very simple tasks).
3. Create knowledge that can be referenced.
4. Avoid /compact and auto-compacting.

I've been using Air since switching to Positron and have been loving it. My only criticism is the styling of tibbles (it just breaks them). Apparently that has been solved

The fastest way to start using & exploring the new 2024 1-year ACS data?
R with tidycensus + mapgl.
With just a few lines of code, you can pull down any of the thousands of variables available in the new data and explore on an interactive MapLibre map.

I was loving Claude Code... until I tried it with #rstats. Constant errors, wouldn't use the tidyverse even when asked, "optimized" functions were slower.
Frustrated, I started a session just to teach R to Claude and summarize what it learned into a CLAUDE.md file gist.github.com/sj-io/3828d6...

As a 10+ year R & Python user, the irony is that 2025 is the best time EVER to be using R.

Almost reaching 100 posts in my blog restateinsight.com/blog.
Feel like it's time to reorganize things. I created this blog back in 2019 to post R tutorials on econometrics and data visualization. I posted everything in Portuguese since I felt there was lack of R-related materials in Portuguese.

Overall, Positron has some great benefits over RStudio. It's faster, lighter, and after some customization looks a lot nicer.
There are still issues. The main one that comes to mind is the overall inferior autocomplete.
Also, autocomplete for Quarto docs seems to breakdown at some point.

Last month I tried to pick up Positron as my main IDE. First two weeks were rough and I found myself going back to RStudio some times for both Quarto and R.
After much stress I am now using Positron daily.
The process did make me realize how much of a petty person I am when it comes to IDEs.
