{tinytable} 0.14.0 for #RStats makes it super easy to draw tables in html, tex, docx, typ, md & png.
There are only a few functions to learn, but don't be fooled! Small 📦s can still be powerful.
Check out the new gallery page for fun case studies.

#rstats polars 1.0.0 is now available!
polars provides bindings to the eponymous Rust library, a very efficient dataframe library.
This is the outcome of a 1-year long rewrite led by @eitsupi to refactor the internals and match the API of Python polars.

Polars has gotten 4x faster than Polars! 🚀
In the last months, the team has worked incredibly hard on the new-streaming engine and the results pay off. It is incredibly fast, and beats the Polars in-memory engine by a factor of 4 on a 96vCPU machine.
