ReLTER vs xplainfi: at a glance
What is ReLTER?
An interface to Europe's long-term ecosystem research network that went quiet after 2.0.
ReLTER provides programmatic access to the eLTER network — the European long-term ecosystem research infrastructure — pulling site metadata, datasets and activities from DEIMS-SDR and enriching them with taxonomic resolution via PESI and WORMS and raster layers from European OpenDataScience. Version 1.0.0 consolidated the function surface and passed into rOpenSci review; 1.1.0 addressed the reviewers' feedback and added vignettes and a Docker install path. Version 2.0.0 was tagged in late 2022 with release notes consisting only of a merge commit message, and nothing has shipped since.
What is xplainfi?
xplainfi treats feature importance as an estimate with error bars, not a number.
xplainfi implements feature importance methods for mlr3 — perturbation-based PFI, CFI and RFI, refit-based LOCO and WVIM, and SAGE. Its defining choice is that importance scores come with inference attached: several confidence-interval methods, including the Nadeau-Bengio correction and a distribution-free option added in 1.1.0. It declared itself released at 1.0.0 in January 2026.

◆ Current state
ReLTER provides programmatic access to the eLTER network — the European long-term ecosystem research infrastructure — pulling site metadata, datasets and activities from DEIMS-SDR and enriching them with taxonomic resolution via PESI and WORMS and raster layers from European OpenDataScience. Version 1.0.0 consolidated the function surface and passed into rOpenSci review; 1.1.0 addressed the reviewers' feedback and added vignettes and a Docker install path. Version 2.0.0 was tagged in late 2022 with release notes consisting only of a merge commit message, and nothing has shipped since.
◆ Where it's heading
The visible arc runs from a scattered set of getSite* functions to a reviewed, documented package, and then stops. The absence of notes on the 2.0.0 tag makes it impossible to say from this feed what that major version changed, and the three-year silence afterwards is the more informative signal. What the package does remains useful — the eLTER data it wraps has no other R interface — but the release history gives no evidence of active development.
◆ Prediction
Nothing in these entries supports a confident prediction about future releases; the feed shows a major version with no notes followed by silence. Whether the package is dormant or simply publishing releases elsewhere cannot be determined from what is here.
xplainfi
2.5ANALYTICS
xplainfi treats feature importance as an estimate with error bars, not a number.
◆ Current state
xplainfi implements feature importance methods for mlr3 — perturbation-based PFI, CFI and RFI, refit-based LOCO and WVIM, and SAGE. Its defining choice is that importance scores come with inference attached: several confidence-interval methods, including the Nadeau-Bengio correction and a distribution-free option added in 1.1.0. It declared itself released at 1.0.0 in January 2026.
◆ Where it's heading
Two lines of work run in parallel. The statistical side keeps adding inference options — variance corrections, conditional predictive impact, and the Lei et al. observation-wise loss-difference test — while the computational side attacks the cost of refit-based methods, most recently with a batch_size argument that parallelises refits and a default of one refit per resampling iteration. Support for pre-trained learners in 1.1.0 removes the refit requirement entirely in some workflows.
◆ Prediction
The stated reasoning that budget is better spent on resampling iterations than repeated refits suggests n_repeats may be removed from WVIM and LOCO outright, as the release notes hint.
