churon vs tEDM
A side-by-side editorial comparison of churon and tEDM — release velocity, themes, recent moves, and the top alternatives to consider.
churon vs tEDM: at a glance
What is churon?
churon is spending its entire release history getting a Rust ONNX binding through CRAN.
An R package wrapping ONNX Runtime through Rust. All three releases in the window land within four days and none of them adds a feature. 0.1.8 downgrades the ort crate to 2.0.0-rc.10 because rc.11 needs Rust Edition 2024 and CRAN's Windows machines run Rust 1.81. 0.1.10 removes the vendored Rust sources from git into a compressed tarball for offline builds, fixes the Windows extraction path, deletes dead Rust and R code, and bumps ONNX Runtime to 1.23.2.
What is tEDM?
The temporal half of the stscl EDM pair, tracking its spatial sibling
tEDM applies empirical dynamic modeling to time series — cross mapping, convergent cross mapping and the logistic map — as the temporal counterpart to spEDM, with which it shares a maintainer and a C++ core. The recent releases are consolidation rather than expansion: index handling in cross mapping corrected, generics taught to accept varying E, k and tau, and the associated paper now cited in the README. Only three releases are visible in the feed.

◆ Current state
An R package wrapping ONNX Runtime through Rust. All three releases in the window land within four days and none of them adds a feature. 0.1.8 downgrades the ort crate to 2.0.0-rc.10 because rc.11 needs Rust Edition 2024 and CRAN's Windows machines run Rust 1.81. 0.1.10 removes the vendored Rust sources from git into a compressed tarball for offline builds, fixes the Windows extraction path, deletes dead Rust and R code, and bumps ONNX Runtime to 1.23.2.
◆ Where it's heading
Every visible decision is set by CRAN's build environment rather than by the package's own roadmap — pinned to an older ort release, vendored dependencies restructured for offline builds, and a dedicated CI job that simulates CRAN without network access. That is the standing cost of shipping a Rust-backed inference binding through R's distribution channel, and it is consuming the release stream entirely.
◆ Prediction
Expect the ort pin to move forward only when CRAN's Windows toolchain reaches a newer Rust, since that constraint is stated explicitly as the reason for the downgrade.
tEDM
0.0ANALYTICS
The temporal half of the stscl EDM pair, tracking its spatial sibling
◆ Current state
tEDM applies empirical dynamic modeling to time series — cross mapping, convergent cross mapping and the logistic map — as the temporal counterpart to spEDM, with which it shares a maintainer and a C++ core. The recent releases are consolidation rather than expansion: index handling in cross mapping corrected, generics taught to accept varying E, k and tau, and the associated paper now cited in the README. Only three releases are visible in the feed.
◆ Where it's heading
tEDM moves in lockstep with spEDM. Configurable distance metrics, varying E/k/tau inputs, strict floating-point comparison and the S3 plotting font unification all appear in both packages within days or weeks, as does the maintainer surname correction. The recent balance has tilted toward correcting library and prediction index handling — the kind of repeated attention that suggests the indexing model was the weak point of the shared core.
◆ Prediction
Expect tEDM to keep inheriting the shared-core changes spEDM lands, with its own releases staying small and centred on cross-mapping parameter handling rather than new method surface.
