I last posted here about 6 months ago. Here's what I've been working on and/or thinking about. #rstats, #statistics, #ml

package upkeep: we are doing major preventive maintenance on the tidymodels packages ("upkeep week!"). It's rote but very rewarding work. Error messages are 100x better.

For more than a year I have been working on a brand new Jupyter Notebook editor for Positron. This is a ground-up build of a new Jupyter Notebook experience built to leverage all the knowledge and tools Posit/Positron brings to the data science table. 🧵#jupyter

dplyr 1.2.0 is out now and we are SO excited!

- `filter_out()` for dropping rows

- `recode_values()`, `replace_values()`, and `replace_when()` that join `case_when()` as a complete family of recoding/replacing tools

These are huge quality of life wins for #rstats!

I sent 200 pull requests using Claude Code and wrote about the experience. It's pretty wild!

For dplyr releases, we send a PR any time we break an #rstats package. This release advances a lot of deprecated functions, triggering issues in many old packages!

I’m not aware of an Arrow or Parquet format, but there is the ONNX format (see onnx.ai). Depending on the model, you could try Posit’s orbital project, which translates your model to SQL (see here orbital.tidymodels.org).

I'm excited to share a new version of the Air formatter for #rstats, with support for tabular formatting! Super useful with `tibble::tribble()` calls or `data.table::fcase()`.

It's currently experimental as we're looking to get feedback on the feature, so please let us know what you think.
