What is Nematode?

A nematode ecology toolbox whose last two releases corrected the arithmetic in its own indices.

Nematode packages the standard soil-nematode community indices — maturity, enrichment, structure and channel indices, trophic diversity, plant parasite index — alongside ordination helpers and a bundled taxonomy and traits dataset drawn from Nemaplex. The visible history is short: a large function drop in 0.2.0, then a run of releases correcting formulas and refreshing the reference data.

What is usmapdata?

usmapdata ships its 2025 shapefiles on the year-indexed model it adopted in 0.4.0.

usmapdata supplies the boundary data behind usmap's plotting functions. Since 0.4.0 it has been year-indexed: us_map(data_year = ) selects a vintage, and each Census release is added as its own year with older ones still reachable. 1.1.0 adds 2025. 1.0.0 closed the package's longest-standing gap by adding Puerto Rico, retroactively across every vintage.

Nematode vs usmapdata: editorial side-by-side

Nematode
INFRA · APIS
0.0

A nematode ecology toolbox whose last two releases corrected the arithmetic in its own indices.

◆ Current state

Nematode packages the standard soil-nematode community indices — maturity, enrichment, structure and channel indices, trophic diversity, plant parasite index — alongside ordination helpers and a bundled taxonomy and traits dataset drawn from Nemaplex. The visible history is short: a large function drop in 0.2.0, then a run of releases correcting formulas and refreshing the reference data.

◆ Where it's heading

Two of the four documented releases fix a formula in an index the package already shipped — the Species Richness Index in 0.2.1 and a missing division by two in the Functional Metabolic Footprints calculation in 0.3.1 — and the 0.2.1 note tells users their earlier values were wrong. That, more than the feature additions, is what the feed records. The other thread is keeping the bundled taxonomy current against Nemaplex, which grew the genus table from 2,484 to 2,524 entries and the body-mass table from 987 to 1,094 in March.

◆ Prediction

Given the pattern of index formulas being corrected after release, further verification of the remaining indices against their source publications is the likeliest next work. The Nemaplex datasets carry a revision date and are refreshed on the upstream schedule, so another data update is the other predictable item.

2.5

usmapdata ships its 2025 shapefiles on the year-indexed model it adopted in 0.4.0.

◆ Current state

usmapdata supplies the boundary data behind usmap's plotting functions. Since 0.4.0 it has been year-indexed: us_map(data_year = ) selects a vintage, and each Census release is added as its own year with older ones still reachable. 1.1.0 adds 2025. 1.0.0 closed the package's longest-standing gap by adding Puerto Rico, retroactively across every vintage.

◆ Where it's heading

The package has settled into a predictable rhythm — one shapefile vintage per year, with structural change rare and clustered. The two changes that mattered were data_year in 0.4.0, which turned a single-vintage dataset into a time series, and the tibble-to-data-frame switch in 0.6.0 that reduced what downstream callers have to depend on.

◆ Prediction

The stated policy — each year added going forward, previous years reachable through data_year — points to a 2026 vintage as the next release. Nothing in these notes suggests further change to the data model.
