dvir vs resmush
A side-by-side editorial comparison of dvir and resmush — release velocity, themes, recent moves, and the top alternatives to consider.
dvir vs resmush: at a glance
What is dvir?
dvir keeps making disaster victim identification a single call instead of a workflow.
dvir handles disaster victim identification: matching unidentified remains against reference families using pedigree likelihoods. The package has consolidated around dviSolve(), a complete pipeline introduced in 3.2.1 and rewritten in 3.3.0 to use generalised likelihood ratios for families with several missing persons. Recent releases have been about making that pipeline survive large cases, adding dviGridSize() and a maxAssign cutoff to skip joint analysis when the combination count explodes, plus per-step timings.
What is resmush?
resmush declared itself finished and has shipped nothing but maintenance since.
resmush compresses images through the reSmush.it API from R. Version 1.0.0 was an explicit maturity statement rather than a feature release: the major version was bumped to signal a stable development state, the minimum R version moved to 4.1.0, and documentation moved to Quarto. The two releases since are console message polish, an internals refactor, and mock-based tests.

dvir keeps making disaster victim identification a single call instead of a workflow.
◆ Current state
dvir handles disaster victim identification: matching unidentified remains against reference families using pedigree likelihoods. The package has consolidated around dviSolve(), a complete pipeline introduced in 3.2.1 and rewritten in 3.3.0 to use generalised likelihood ratios for families with several missing persons. Recent releases have been about making that pipeline survive large cases, adding dviGridSize() and a maxAssign cutoff to skip joint analysis when the combination count explodes, plus per-step timings.
◆ Where it's heading
The arc is from a toolbox of functions toward one supervised pipeline, with the older jointDVI() now emitting a legacy message. The current constraint is combinatorial: joint analysis over many victims and missing persons blows up, so the work has gone to measuring the blowup and bailing out of it. Parallelism is mid-migration, with the parallel and pbapply implementation removed and a mirai replacement stated as planned but not yet shipped, leaving numCores accepted and ignored with a warning.
◆ Prediction
The mirai-based parallelisation is announced as coming, so expect it next, most likely applied to the joint analysis step that maxAssign currently exists to avoid.
resmush
0.0ANALYTICS
resmush declared itself finished and has shipped nothing but maintenance since.
◆ Current state
resmush compresses images through the reSmush.it API from R. Version 1.0.0 was an explicit maturity statement rather than a feature release: the major version was bumped to signal a stable development state, the minimum R version moved to 4.1.0, and documentation moved to Quarto. The two releases since are console message polish, an internals refactor, and mock-based tests.
◆ Where it's heading
This is a package in maintenance by design. The functional surface has not changed since 0.2.2 added a dry-run check and a referer header to the API calls, and the notable earlier change was subtractive, dropping webp when the upstream API stopped accepting it. Recent activity is dominated by dependency bumps and testing work, with mocks replacing live API calls in the test suite.
◆ Prediction
Expect the same maintenance cadence, with the most likely source of a real change being another format or endpoint shift at the reSmush.it API rather than anything originating in the package.
