checkhelper vs Nematode: at a glance
What is checkhelper?
checkhelper grew from a check wrapper into a CRAN pre-submission auditor.
1.0.0 added a whole audit_* family — audit_downloads(), audit_description(), audit_dontrun() and audit_citation() — each parsing package source statically and returning a tibble of hits paired with a suggested fix. The package is now defending that position: 1.0.1 rc1 is a submission candidate answering a CRAN archival notice, after roxygen2 8.x moved DESCRIPTION's RoxygenNote field and broke a find_missing_tags() test fixture.
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.

checkhelper grew from a check wrapper into a CRAN pre-submission auditor.
◆ Current state
1.0.0 added a whole audit_* family — audit_downloads(), audit_description(), audit_dontrun() and audit_citation() — each parsing package source statically and returning a tibble of hits paired with a suggested fix. The package is now defending that position: 1.0.1 rc1 is a submission candidate answering a CRAN archival notice, after roxygen2 8.x moved DESCRIPTION's RoxygenNote field and broke a find_missing_tags() test fixture.
◆ Where it's heading
The design commitment is static analysis — AST walks via getParseData(), line-by-line Rd reading, no eval() and no namespace loading — so the tool can report on a package it never runs. That commitment is what made the roxygen2 8.x break survivable: the audit pipeline itself was verified correct under 8.1.0 and only the test scaffolding had to go, now guarded by a dedicated regression test. fix_globals(write = TRUE) is being sanded down in parallel, no longer flattening per-function grouping comments or writing a degenerate empty globalVariables() shell.
◆ Prediction
The immediate move is the 1.0.1 submission itself, clearing the archival notice. Beyond that, each additional CRAN incoming-check rule remains a candidate for another audit_* function; the open question these notes still leave is whether the family ever gets a single combined entry point.
Nematode
0.0INFRA · APIS
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.
