Plot life expectancy against GDP per capita for 2007, with a regression line.
Filtered gapminder to 2007 into gm_2007 (142 countries). Plotted lifeExp against log(gdpPercap), with a linear geom_smooth on top.
Life expectancy vs GDP per capita
Gapminder, 2007 (log x)
Richer countries tend to live longer. The log-linear fit explains about 66% of the variance. Countries sitting well below the line typically had acute public-health crises in the 2000s.
Want me to color the points by continent, fit separate slopes per region, or compare this against 1957 to see how the trend has shifted?

01 — Capabilities

Everything you ran in RStudio, and an agent who actually reads the docs.

01

An agent that writes R

Describe the analysis. The agent drafts the code, runs it, reads the output, and iterates. It shows its work, cites what it used, and never sends your data anywhere. Calls go from your browser directly to your LLM provider.

02

The R you know

dplyr, ggplot2, lubridate, stringr: the full tidyverse compiled to WebAssembly. Fit models, draw plots, write pipelines just like you would locally. A full R session boots in a few seconds.

03

Work anywhere, iterate fast

Open a project on a Chromebook, pick it up on your laptop. A live R REPL, instant ggplot previews, and a DuckDB-backed table that stays responsive on millions of rows. No VPN, no setup, no tears.
