provenance$coverage's n_units_reporting is category-conditional: it
counts governments with rows for the SPECIFIC requested category, which
conflates two different things -- a government never collected that
year (sampling), and one collected but genuinely spending nothing in
that category (a real zero). FY2012 Georgia Police is the motivating
case from the issue: a complete census year reads as a 69% "response
rate" because most of the gap is cities that contract policing to the
county sheriff, not non-response.
Adds a second counter, n_units_collected: how many of the caller's
expected cohort appear in the corpus that year for ANY category.
n_units_collected / n_units_expected is the true collection rate;
n_units_reporting / n_units_collected is category participation among
collected units. cog_geographic_rollup() and cog_peer_compare() both
carry it; cog_explain() prints it alongside n_units_reporting.
Two real bugs caught and fixed while finishing this (both against the
already-written, previously-uncommitted draft):
- .coverage_table()'s candidate list for the collection query was
derived from the category-filtered result rows, not the caller's
full expected cohort. A government with zero rows in the requested
category across every requested year never appears in that result,
so it was silently excluded from n_units_collected too -- collapsing
the new counter back to the old, broken one for exactly the
governments it exists to count. Fixed by threading an explicit
`expected_ids` (all_govids / peer_govids) through instead.
- The collection query hardcoded long_view = "spending_long_harmonized",
which does not exist on a corpus with schema_version < 5 (R/basis.R
resolves basis = "raw" there; R/views.R only registers the
harmonized views on v5+). cog_geographic_rollup()/cog_peer_compare()
would hard-error on a corpus vintage the package otherwise explicitly
supports. Fixed by deriving long_view from the basis cog_spending()
actually resolved (prov$basis) via the existing .select_long_view()
helper, matching how every other basis-aware query in the package
already does this.
Also: cog_explain()'s general "complete census only in years ending in
2 or 7" footnote was gated on the OLD counter's absence, making it
permanently unreachable now that both callers always supply the new
one -- ungated it, since the explanation is orthogonal to which
counter set is present. Dropped a dead conditional branch, fixed two
stale roxygen blocks in R/peers.R/R/rollup.R still describing the old
two-counter model, fixed the same staleness in README.md, and switched
two `uscogdata:::` self-references to the package's own convention of
calling internal helpers unqualified.
1101 tests pass (2 skipped live-corpus), including new direct
regression tests for both bugs above (one exercising a government
collected-but-absent from a category result, one running the full
rollup/peer-compare path against a doctored schema_version 4 corpus).
Reviewed by an independent code-reviewer pass (1 HIGH, 1 MEDIUM, 3 LOW
-- all addressed above).
Closes#36.
