When I say that Claude is very good at coding in R, there are caveats.

As G10 countries succumb to simplistic populism, reckless fiscal policy and fiscal dominance of their central banks, the line between the G10 and EM is getting blurred. Real long-term interest rates in the G10 have begun to rise towards EM levels...

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...

Saw a post from an influencer telling followers to "stop using R for anything -- use Python like a normal person"

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

Here's why:

What a great piece on online advertising. Summarizes beautifully my frustrations when working as a data scientist (with econ background) in a big marketing department.

Leaders justified decisions with bad metrics, fueled by biased samples.

Forgot some Positron shoutouts,

@andrew.heiss.phd has a nice post talking about Positron (www.andrewheiss.com/blog/2024/07...) and Albert Rapp also has one (3mw.albert-rapp.de/p/using-the-...)

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.

Still missing some plots, but wanted to share this one.

Day 25 #30DayChartChallenge | Uncertainties: Risk

The plot shows the "Brazil Risk" measured by the EMBI+ and highlights key economic/political events. This index broadly measures the risk that foreign investors face when investing in Brazil.

This chart shows the deforestation of the Amazon rainforest over the years, based on satellite imagery.

This year's COP30 will take place in Belém, Pará—a state that has consistently ranked among the top 2 in deforestation, since 1988.

Day 29 #30DayChartChallenge | Uncertainties: extraterrestrial

For day 29, I aggregated U.S. box office numbers for movies featuring aliens—any kind of extraterrestrial life counts. Alien sci-fi really dipped between 1986 and 1995 (Predator 2, Alien 3, Coneheads...).

Day 4 #30DayChartChallenge | Comparisons: Big or Small

Choropleth maps of Brazil can be very deceiving. The Midwest and North regions cover about 65% of the country’s area but house only 16% of its population.

Maps show Aging Index: ratio of the pop. aged 65 and over to those aged 14 and under.
