What is ribd?

The pedsuite's coefficient engine: broadening what it computes, then making the plots publishable.

ribd computes relatedness coefficients from pedigrees, covering kinship, inbreeding, kappa, condensed and detailed identity coefficients, and two-locus versions of several of these, in autosomal and X-chromosomal form. The IBD triangle is now drawable in base graphics, ggplot2 or plotly, with an optional inset pedigree, and custom relationships can be placed on it. The most recent release is dominated by correctness work, fixing pair ordering and row alignment in coefficient tables and edge cases for pedigree lists, unrelated individuals and self-pairs.

What is StreamCatTools?

StreamCatTools is quietly moving off web services and onto cloud-native GeoParquet

StreamCatTools is the R client for the US EPA's StreamCat and LakeCat watershed metrics datasets. Through 2025 it worked almost entirely against the StreamCat web API, and much of its release history is about making those HTTP calls survive real conditions — POST bodies for long COMID lists, tryCatch around service outages, tests that skip when the service is down. 0.11.0 in May 2026 introduces a different data path.

The pedsuite's coefficient engine: broadening what it computes, then making the plots publishable.

◆ Current state

ribd computes relatedness coefficients from pedigrees, covering kinship, inbreeding, kappa, condensed and detailed identity coefficients, and two-locus versions of several of these, in autosomal and X-chromosomal form. The IBD triangle is now drawable in base graphics, ggplot2 or plotly, with an optional inset pedigree, and custom relationships can be placed on it. The most recent release is dominated by correctness work, fixing pair ordering and row alignment in coefficient tables and edge cases for pedigree lists, unrelated individuals and self-pairs.

◆ Where it's heading

The arc runs from generality to presentation to precision. Early releases replaced narrow functions with general ones, most visibly when gKinship() absorbed generalisedKinship() and identityCoefs() superseded the separate autosomal and X-chromosomal identity functions in favour of an Xchrom argument. The middle stretch turned the IBD triangle into a proper plotting surface across three graphics systems. The current phase reads as consolidation, with the newest release listing six bug fixes against four features, several of them alignment errors in output tables, which is where a coefficient library most needs to be exactly right.

◆ Prediction

The two new internal functions in the latest release, inbreedingContributions() and ancestralKinship(), are the kind of thing that surfaces publicly a release or two later, so expect them to become exported decomposition tools. The correctness push through pedigree lists and edge cases suggests the near-term focus stays on hardening rather than new coefficient families.

S0.0

StreamCatTools is quietly moving off web services and onto cloud-native GeoParquet

◆ Current state

StreamCatTools is the R client for the US EPA's StreamCat and LakeCat watershed metrics datasets. Through 2025 it worked almost entirely against the StreamCat web API, and much of its release history is about making those HTTP calls survive real conditions — POST bodies for long COMID lists, tryCatch around service outages, tests that skip when the service is down. 0.11.0 in May 2026 introduces a different data path.

◆ Where it's heading

The newest release adds lc_get_watershed(), which returns a lake watershed as an sf feature by reading an S3-hosted, HUC2-partitioned GeoParquet dataset with DuckDB, optional HUC2 filtering, retries and multi-threading. That is a materially different access model from the web service the rest of the package uses. Alongside it, 0.10.0 added National Nutrient Inventory access and nitrogen/phosphorus budget plotting, extending the package past retrieval into presentation.

◆ Prediction

If the GeoParquet path proves faster and more reliable than the web service, migrating more retrieval functions onto it is the obvious next move. The entries do not say whether EPA intends to publish the full metric catalogue in that format.
