OpenTelemetry has come to R 🎉

We've instrumented Shiny, plumber2, mirai, httr2, ellmer, knitr, testthat, and DBI — so you can get production-grade traces from your R apps with no code changes. Just set a few env vars and telemetry flows to the backend of your choice.

Bringing OpenTelemetry to R in production

Posit has instrumented Shiny, plumber2, mirai, httr2, ellmer, knitr, testthat, and DBI with OpenTelemetry, and created tools for you to instrument your own packages, bringing production-grade observability to R.

In an R package, I am linking against R's LAPACK but ideally would like to have access to the the single precision float routines, which are not bundled there (on windows) because R does not use them. Does anyone have a recommendation how to also get access to f32 routines on windows? #rstats

One thing which might be nice is to have a ..(n) function that allows to skip n dimensions, so slicing the fourth dimension would become x[..(3), i, ..]

as more and more code is produced by LLMs I think it becomes even more important for code to be intuitive and readable.

Generally one pain is the:" select i-th axis, where i is a variable", because you can't do x[,,,2] because you don't know how many of those ","s you need.

What's the best "data.table"-like DSL for n-dimensional arrays? I am already aware of DumPy: https://dynomight.net/dumpy/

I am exploring ideas how to make array computations more readable. #rstats

DumPy: NumPy except it’s OK if you’re dum

Why do I have to write C Code in R to pre-allocate a vector with a certain capacity? #rstats

Big new release in {anvl} (formerly called anvil, which conflicted with the AnVIL bioconductor package): https://github.com/r-xla/anvl/releases/tag/v0.2.0

There are too many features to list here, but one of the biggest ones is the introduction of eager mode, so usability of the package should be greatly improved!

Release anvl 0.2.0 · r-xla/anvl

Breaking Changes The package was renamed from anvil to anvl to avoid a conflict with the Bioconductor package AnVIL. AnvilTensor/nv_tensor were renamed to AnvlArray and nv_array to be more in line...

Has someone managed to publish a package on CRAN that downloads some prebuilt binaries? The C++ library I depend on uses LLVM and MLIR and the build is pretty complicated and I would really not like to maintain it as part of the CRAN package. #rstats
