islands dataset gains five coordinate columns
(WGS84 decimal degrees): latitude/longitude (a
representative point on each territory’s main landmass) and
capital/capital_latitude/capital_longitude
(the capital city). Sourced from Natural Earth with a hand-curated
supplement for the BES islands, French overseas departments, and other
small territories; see the upstream
island-research-reference-data for provenance.island_coords() returns coordinates for a vector of
names or ISO codes, with which = "point" (default) or
which = "capital".island_distance() gives great-circle (haversine)
distances between islands: a full symmetric matrix among one set, or
element-wise/recycled distances between two. Supports which
(point or capital) and unit (km, mi, nmi). Base R, no new
dependencies.islands. Its
ISO 3166-1 alpha-2 code is the literal string "NA", which
the data-build step previously treated as a missing value. The dataset
now has 251 rows (was 250).Resubmission addressing CRAN reviewer feedback (Uwe Ligges).

islands reference dataset: 250 countries and
territories with classifications for SIDS, SNIJ, World Bank region and
income group, political association, and the four small-island defining
criteria.is_sids(), is_snij(),
is_small_island() accept country names, ISO codes, or the
hyphenated BES sub-codes (BQ-BO, BQ-SE,
BQ-SA).island_lookup() and add_island_cols() for
tidy joining onto research data.small_islands() shorthand for filtered subsets.aruba() — A.R.U.B.A. (Annotated Reference for
Under-coded Border Areas): a convenience wrapper around
island_lookup() with Aruba as the default. A homage to
