L1centrality vs medicalcoder: at a glance
What is L1centrality?
A graph-centrality package that spent 2026 making its existing measures usable at scale, then went quiet.
L1centrality implements L1 centrality and prestige for graphs, including group, local, and neighbourhood variants plus MDS-based visualization. The measure set has been stable since 0.3.0; the work since has gone into interfaces around it — S3 classes with print and summary methods, plot methods for every result class, and in 0.5.0 both multi-group evaluation and multicore computation for the local variant. The two releases since have been a warning-message pass and a typo pass.
What is medicalcoder?
A comorbidity-coding package relicenses to BSD and grows past the American coding systems
medicalcoder maps ICD diagnosis codes to comorbidity conditions using the Charlson, Elixhauser, AHRQ and PCCC method families. Three releases since June 2026 moved it from a US-centric tool to one carrying Australian and Swedish modifications, added four new Charlson variants, and introduced a choice between precomputed code-condition links and regex mapping applied directly to input codes. The license moved from GPL-2 to BSD 3-Clause along the way.

A graph-centrality package that spent 2026 making its existing measures usable at scale, then went quiet.
◆ Current state
L1centrality implements L1 centrality and prestige for graphs, including group, local, and neighbourhood variants plus MDS-based visualization. The measure set has been stable since 0.3.0; the work since has gone into interfaces around it — S3 classes with print and summary methods, plot methods for every result class, and in 0.5.0 both multi-group evaluation and multicore computation for the local variant. The two releases since have been a warning-message pass and a typo pass.
◆ Where it's heading
The package has moved from defining measures to operationalizing them. 0.5.0 was the inflection: parallel local computation and list-valued group input both target users running these measures over many vertex sets or large graphs rather than illustrating them on one. The same release renamed weight_transform and eta to edge_weight_transform and vertex_weight, and added an explicit message when a distance matrix is received — the signature of a maintainer fielding the same misuse repeatedly.
◆ Prediction
The last two releases carry no functional change, so the near-term path is maintenance rather than new measures; a 0.6.0 would most likely extend parallelism beyond L1centLOC to the other computationally heavy variants.

A comorbidity-coding package relicenses to BSD and grows past the American coding systems
◆ Current state
medicalcoder maps ICD diagnosis codes to comorbidity conditions using the Charlson, Elixhauser, AHRQ and PCCC method families. Three releases since June 2026 moved it from a US-centric tool to one carrying Australian and Swedish modifications, added four new Charlson variants, and introduced a choice between precomputed code-condition links and regex mapping applied directly to input codes. The license moved from GPL-2 to BSD 3-Clause along the way.
◆ Where it's heading
Two things are happening at once. The coding surface is broadening — ICD-10-AM, ICD-10-SE, Swedish register-based and MIMIC-IV-consistent Charlson methods — which points at users outside the US claims-data world. Separately, the package is hardening: validation on encounter ordering, deterministic result ordering, NA rather than NaN for zero counts, and corrected AHRQ and Quan mappings for fiscal years 2023 to 2026. The mapping argument is the first real fork in how the computation runs rather than what it covers.
◆ Prediction
Regex mapping is currently unavailable for charlson_beyrer2021 and the release notes flag it as a gap, so closing that is the most clearly signposted next step.
