Recreating things made with other technologies is a great way to learn!

My favourite way to incorporate {gt} tables in Quarto rendered typst reports, along with `#show figure: set block(breakable: true)`{=typst} #rstats #quarto

Does anyone have a go-to guide for deploying {plumber} REST APIs on an on-premise server using Docker and Nginx? #rstats I used a tutorial earlier in the year, but I can't find it for some reason.

I was skeptical at first, it has largely overtaken RStudio. Only issue I encountered early on was the View function in #Positron being different to RStudio.

A grid of bar charts showing the average weekly price of regular grade gasoline in the United States from 1993 to 2025, grouped by decade and year. Each bar represents a week, colored by the difference from the yearly mean price. The color scale ranges from deep blue for below-average weeks to orange for above-average weeks.

I don't. I usually look at Excel to check the quality of the output before forwarding it to a stakeholder. I haven't used MS products in so long, I need to remind myself of basic functionality from time to time.

Starting to look like I might not be able to work at Harvard anymore due to recent funding cuts. If you know of any open statistical consulting positions that support remote work or are NYC-based, please reach out! 😅

At least you all are looking into different operators. I have been using %in% with negation. I will try these two out.
