[#]rstats polars 0.20.0 is now available!

This isn't a huge release, but there are still a few additions (and a couple of breaking changes). In particular, polars can now perform inequality joins using the new $join_where() functions (limited to inner joins for now).

[#]rstats Introducing a new package: flint!

{flint} is a package to find lints (~ "bad practices") in R code and automatically fix them. {lintr} does a great job but doesn't fix lints and can be slow on large codebases.

The everyday usage is quite simple: use lint() and its variants to show lints, and use fix() and its variants to automatically fix them (not all lints can be fixed).

[#]rstats New blog post: using property-based testing in R.

This briefly explains what property-based testing is and presents a couple of situations where it can be useful when developing R packages.

[#]rstats I've given a very lightweight presentation on handling large data with polars and tidypolars (for a non-technical audience).

It's not a tutorial, there is very little code. I think it can be useful as a first step to understand what are some problems that one faces with large data (such as order of operations) and how polars can help with that.

As usual, a new {polars} release is accompanied by a new {tidypolars} release (v.0.10.0).

This contains:

• wrapper functions for reading / scanning data, so that users don't need the syntax pl$read_parquet() anymore

• better error messages

• support for more functions and arguments

• some deprecations to better match the {dplyr} API

• several bug fixes

The R package {polars} version 0.19.1 is now available!

In particular, this brings better support for reading and writing hive partitions for Parquet and IPC files, and it adds several functions to deal with string, list, and binary columns.

As usual, this release also contains performance improvements and breaking changes (some parameters are renamed, some functions are removed, etc.) so it's important to check the changelog: https://pola-rs.github.io/r-polars/NEWS.html#polars-r-package-0190
