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.
