mev vs rdataone: at a glance
What is mev?
An extreme-value toolkit reorganised its whole API into prefixed families and tripled its estimator count.
mev provides likelihood-based inference for univariate and multivariate extreme value models — threshold selection, shape estimation, tail dependence and max-stable simulation. Version 2.0 was a deliberate reorganisation: every threshold-selection routine now carries a thselect. prefix, every stability plot a tstab. prefix, and every extremal-dependence measure an xdep. prefix, with the old names deprecated but mostly still working. The same release added a large batch of estimators — Stein-weighted GPD, roughly a dozen shape estimators, second-order regular variation, L-moment GPD and Weissman quantiles.
What is rdataone?
The R client for DataONE ships slow, correctness-focused maintenance
rdataone is the R client for the DataONE federated research-data network, handling authentication, upload and retrieval of data packages against member nodes. Recent work is concentrated on correctness in the upload path — rightsHolder persistence, public-read flags applied across all objects in a package, and edge cases in archive() — plus dependency trimming. The feed's version stamps are unreliable: 2.2.2 carries a later publication date than 2.3.0, which cites 2.2.2 as its own predecessor.

An extreme-value toolkit reorganised its whole API into prefixed families and tripled its estimator count.
◆ Current state
mev provides likelihood-based inference for univariate and multivariate extreme value models — threshold selection, shape estimation, tail dependence and max-stable simulation. Version 2.0 was a deliberate reorganisation: every threshold-selection routine now carries a thselect. prefix, every stability plot a tstab. prefix, and every extremal-dependence measure an xdep. prefix, with the old names deprecated but mostly still working. The same release added a large batch of estimators — Stein-weighted GPD, roughly a dozen shape estimators, second-order regular variation, L-moment GPD and Weissman quantiles.
◆ Where it's heading
The package is consolidating into a reference implementation of the extreme-value literature rather than a collection of one-off routines. Sixteen threshold-selection methods now share standardised arguments and their own plot and print methods with automatic selection, which is the tell: the goal is comparability across methods, not just availability. Dependency reduction runs alongside, with distribution functions written in-package to drop evd and Rsolnp replacing nloptr in earlier releases.
◆ Prediction
Version 2.1 continued adding threshold-selection routines within the new naming scheme, so the next release most likely follows the same pattern — more estimators fitted to the established prefixes, plus fixes to the 2.0 renaming. The entries give no sign of a further structural change.

The R client for DataONE ships slow, correctness-focused maintenance
◆ Current state
rdataone is the R client for the DataONE federated research-data network, handling authentication, upload and retrieval of data packages against member nodes. Recent work is concentrated on correctness in the upload path — rightsHolder persistence, public-read flags applied across all objects in a package, and edge cases in archive() — plus dependency trimming. The feed's version stamps are unreliable: 2.2.2 carries a later publication date than 2.3.0, which cites 2.2.2 as its own predecessor.
◆ Where it's heading
This is long-cycle infrastructure maintenance, not feature development. Release intervals run to years, and the content is dominated by access-control correctness, CRAN compliance and TLS/platform fixes rather than new client capability. The one consistent thread is hardening how permissions and checksums survive a round trip to a member node.
◆ Prediction
Expect continued low-frequency releases driven by CRAN check failures and platform TLS changes, with any functional work staying in the upload and permissions path rather than the query surface.
