Support for the 2026-06-26 release and its new monthly-aggregate schema, plus a live fallback so releases published after a package version was built remain reachable.
release_2026_06_26 (April
and May 2026 data, monthly cadence, Artifacts metrics, “Cadences”
report).aei_index() recognises the monthly filename convention
(aei_<source>_<date>.csv; the raw/enriched
variant was dropped from filenames) and the new monthly schema. The
variant argument is ignored for monthly releases. If a
release breaks the filename convention expected for its epoch, the other
epoch’s pattern is tried before erroring.aei_geography() understands the monthly schema’s
geo_level column and ISO 3166-2 subregion codes, gains a
"subregion" level, maps "state_us" onto US
subregions (geo_id starting "US-") for monthly
releases, and now defaults to release = "latest".aei_compare() chooses its default join keys from the
schema the two releases share (by = NULL is the new
default) and filters monthly releases, which can ship several calendar
months in one file, to their most recent date_start window
before joining."latest", ids, and dates) now falls
back to the live Hugging Face directory listing when an identifier is
not in the bundled table, so releases published after this package
version was built resolve instead of erroring. The listing is fetched at
most once per session; offline use degrades to the bundled list.aei_index() reports the file size before starting a
download larger than 50 MB (the monthly usage CSVs exceed 200 MB).aei_labor_market() fetches the standalone
labor_market_impacts tables ("job_exposure",
"task_penetration") that Anthropic publishes alongside the
dated releases.aei_concentration() documentation claimed the input
scale was detected automatically; it is not, and the docs now describe
the actual behaviour. A new rescale argument normalises
shares to percentages summing to 100 before computing HHI and CR_n, for
use on filtered subsets whose shares no longer total 100.aei_cite() and aei_releases() now carry a
report URL for the 2026-03-24 release (previously NA).CRAN maintenance release addressing a check-system issue raised by the CRAN team on 2026-05-31.
\donttest{} example for aei_link()
fetched a release file into the persistent user cache
(tools::R_user_dir()) rather than a temporary directory, so
it left data behind on the CRAN check machines. The example now
redirects the cache to tempdir(), matching every other
example in the package.aei_cache_dir() now redirects to a session-temporary
directory when it detects an R CMD check run, so the
package cannot write to persistent storage during checks even if an
example, test, or vignette omits the redirect.bls.gov/soc/ reference link from the help
page and README. The page returns HTTP 403 to automated URL checkers;
the Standard Occupational Classification is still cited by name.Initial release.
aei_releases() lists available Anthropic Economic Index
releases on Hugging Face, blending bundled metadata with a live
listing.aei_files() returns the recursive file tree of a
release.aei_index() fetches the canonical usage CSV for a
release, handling the wide-to-long schema change between the 2025-03-27
and 2025-09-15 releases automatically.aei_download() is the lower-level escape hatch for
fetching any file from a release by path.aei_clusters() returns the request-hierarchy tree (Clio
output) as a parsed nested list. Released from 2025-09-15 onwards.aei_tasks() returns the bundled O*NET task statements
(released with the 2025-03-27 snapshot).aei_geography() filters the long-format enriched table
to country or US-state rows. Released from 2025-09-15 onwards.aei_compare() produces a release-on-release diff of the
same metric across two AEI snapshots, returning shared keys plus
value_a, value_b, delta, and
pct_change.aei_link() is a generic merge helper that preserves the
aei_tbl class and provenance metadata. Use it to splice the
AEI to your own data on a shared key (country code, occupational
identifier, cluster name, etc.). Supports left, inner, and full
joins.aei_concentration() computes the Herfindahl-Hirschman
Index, top-N concentration ratios (CR4 by default), and Shannon entropy
on a vector of usage shares. Auto-detects the share column and supports
per-group computation.aei_cite() returns a citation in plain text, BibTeX, or
bibentry form, including the methodological source paper of
Handa et al.
aei_cache_info(), aei_cache_clear(), and
aei_cache_dir() manage the local data cache.aei_tbl class with print,
summary, and [ methods that preserve the
aei_query provenance attribute (release id, source URL,
fetch timestamp) across subsetting.
