Yep, as someone who both uses lots of R packages and writes lots of R packages (which, in turn, import other R packages), I've grown to appreciate the strictness of CRAN: if a package is on the CRAN, I'm just about guaranteed to n

Absolutely correct. CRAN takes down and rejects packages all the time for minor issues and violations of their rules and guidelines. And there are a lot of them: https://cran.r-project.org/doc/manuals/r-release&#x2

I've done exactly what you're talking about using tree-sitter (via the tarborist VS Code extension), specific to targets pipelines: https://bsky.app/profile/tylermw.com/post/3mjmcykuows2d So yes, it

Yes, the main benefit is caching and reproducibility: with targets (or any other DAG-based approach), you only recompute what needs to be recomputed and you are assured that no stale inputs or temporary analysis artifacts end up in the fina

Thanks for all the work you (and the rest of the contributors) have done putting this together! I think bringing tree-sitter to R has already shown massive benefits: Just air alone has been a big improvement to my workflow.

I read this article a week or so ago and immediately implemented a VS Code extension that I've always wanted: a static analysis tool for targets pipelines. targets is an R package which provides Make-like pipelines for data science and

This is pretty astounding. Honestly, this is the feel-good "our company is helping save dogs" story that should have been featured at the super bowl. The fact that AI can be used by a motivated and smart person to facilitate the p

Nice results! SIMD can be a pain, good to know Zig makes it easy. However, note that the plot under "Native SIMD Throughput Comparison" is extremely misleading: for an accurate proportional comparison between bar charts, you shoul

When you're dealing with large populations (here, the study include 230,065 students--a very large number), even small shifts due to some treatment can be significant. It is very hard to generate top-down policy interventions that shif

There is a way to model this type of situation for watertight dielectrics with interface tracking: you assign each material a priority value, and a transition between materials occurs when entering that material only if it has a higher prio

The developing S7 object system ( https://github.com/RConsortium/S7 ) is looking fairly promising in that it combines many of the nice properties of S3 and S4 (validation, multiple dispatch, sane constructors) while stil

For 28 Years Later, note that while the iPhone sensor did in fact ultimately collect the photons for the movie, they attached substantial professional-grade glass to the front to augment the phone camera.

Importantly, the base R pipe implements the operation at the language parsing level, so it has basically zero overhead.

Yes, you are correct, I should have typed "runs". But the point is that MITRE runs the U.S. National Cybersecurity FFRDC that maintains the CVE system, and FFRDCs are deliberately structured to minimize potential conflicts of inte

trace is great for shimming in your own code to an existing function, but it’s not an interactive debugging tool.

Funny you mention namespacing: R 4.5.0 was just released today with the new `use()` function, which allows you import just what you need instead of clobbering your global namespace, equivalent to python’s `from x import y` syntax. e.g. avoi

For simple operations like the dot product (that also map extremely well to SIMD operations), yes, the CPU is often better, as there not much actual "computation" being done. More complex computations where the data does not need

DuckDB is great for medium data: Too big for memory, but small enough to fit on local storage. It's also extremely performant for loading data and supports a wide range of storage backends. It's also really well integrated with R
