To be effective, data science agents need to be able to read plots reliably. @sara-altman.bsky.social and I wrote about some concerning findings on LLMs' ability to interpret plots when the content contradicts their expectations on the @posit.co blog.

When plotting, LLMs see what they expect to see - Posit
Data science agents need to accurately read plots even when the content contradicts their expectations. Our testing shows today's LLMs still struggle here.

My talk from posit::conf earlier this fall on getting unstuck with #Python is now available to watch!

- Ten years ago, I attempted to learn Python and it went EXTRMELY badly 😩
- I am really happy that so much tooling in this area has improved SO much since then 😌

I gave the closing keynote at posit::conf in September and it's available to watch. When you find yourself giving a talk with a little tiny microphone stuck to the side of your head you have to ask yourself some hard questions, but the talk was partly about that.

We are looking for #rstats community feedback on 3 new dplyr functions!

We're aiming to expand the `filter()` family:

- `filter()` to keep rows
- `filter_out()` to drop rows
- `when_any()` and `when_all()` as modifiers

My keynote about data science tools at posit::conf is now online! I originally meant it to be a talk about Positron, but as I was writing it, it took a left turn through the history of RStudio and into the philosophy of tool design & how to build stuff for people.
