Started as a GitHub wiki, then a #Quarto site… & now finally looks how I imagined. Only 50% done, but it's been fun revisiting 6 years' worth of #r resources.
Hoping it still helps someone out there. 💛

I’ve just published {typeR}, a small R package that lets you simulate live typing. It prints code
To install:
devtools::install_github("fgazzelloni/typeR")
If you teach or demo R, I’d love your feedback on how it works for you. #rstats #rpackages

Data science agents need to accurately read plots even when the content contradicts their expectations. Our testing shows today's LLMs still struggle here.
