r2dii.match vs segregatr: at a glance
What is r2dii.match?
PACTA's loan-book matcher opened up to sector taxonomies other than its own.
r2dii.match links entries in a bank's loan book to companies in the asset-based company data, combining an optional exact join on a shared ID with fuzzy name matching. Since 0.3.0 the sector classification used for that matching is an explicit argument rather than a fixed default, letting institutions bring their own taxonomy. Recent releases have been documentation and messaging work under a new maintainer.
What is segregatr?
A segregation-analysis tool that keeps widening which pedigrees it can actually handle.
segregatr computes full-likelihood Bayes factors for variant segregation in families, built on pedtools and part of the wider pedsuite ecosystem. Its releases are infrequent but each one lifts a structural restriction: loops, recessive and X-linked models, liability classes, and most recently a proband-free variant of the score. The companion shinyseg app gives the same machinery a clinical front end.

r2dii.match
0.0ANALYTICS
PACTA's loan-book matcher opened up to sector taxonomies other than its own.
◆ Current state
r2dii.match links entries in a bank's loan book to companies in the asset-based company data, combining an optional exact join on a shared ID with fuzzy name matching. Since 0.3.0 the sector classification used for that matching is an explicit argument rather than a fixed default, letting institutions bring their own taxonomy. Recent releases have been documentation and messaging work under a new maintainer.
◆ Where it's heading
The package has spent its releases removing assumptions. The ald to abcd migration completed the move to the current data vocabulary, join_id gave users a way to bypass fuzzy matching where they already hold a reliable identifier, and sector_classification opened the taxonomy itself. Each of these hands control back to the user for a decision the package previously made. Activity has since shifted to hygiene — a data_dictionary describing every column, cli-based messaging, documentation edits — and the maintainer handover in 0.4.0 fits that pattern. The data_dictionary landed here two days after the same addition to r2dii.plot, so this is a family-wide convention rather than one package's idea.
◆ Prediction
With the API opened up and a new maintainer settling in, expect continued alignment work across the r2dii family rather than changes to the matching algorithm itself.
segregatr
0.0ANALYTICS
A segregation-analysis tool that keeps widening which pedigrees it can actually handle.
◆ Current state
segregatr computes full-likelihood Bayes factors for variant segregation in families, built on pedtools and part of the wider pedsuite ecosystem. Its releases are infrequent but each one lifts a structural restriction: loops, recessive and X-linked models, liability classes, and most recently a proband-free variant of the score. The companion shinyseg app gives the same machinery a clinical front end.
◆ Where it's heading
The through-line is coverage of awkward real-world pedigrees rather than new statistics. Loops were handled for the core score in 0.3.0 and then extended to liability classes in 0.4.0, so the same structural capability is being pushed through the codebase feature by feature. The 2025 release moves in a different direction, relaxing the requirement for a designated proband. Development is slow and steady, roughly annual, and tracks its pedtools dependency closely.
◆ Prediction
Expect the next release to continue relaxing modelling constraints — the pattern of retrofitting each new capability across loops, liability classes and inheritance models is unfinished — rather than expanding beyond segregation scoring.
