island_region values are now consistently abbreviated
("L", "V", "M") across all
releases. Three older releases (Q4_2023, April_2024, Q2_2024) had full
spellings (“Luzon”, “Visayas”, “Mindanao”) which are now recoded during
the data build step.get_psgc_wide() returns a denormalised wide-format
data frame with one row per barangay and all four geographic levels
(region, province, city/municipality, barangay) spread into columns.
HUC/ICC barangays have city_mun /
city_mun_code set to NA; areas with no
province layer (e.g. Pateros, City of Isabela, Special Geographic Areas)
have province / province_code set to
NA (#get_psgc_wide).
map_psgc() gains a changes_only
argument. When TRUE, only rows where the code actually
changed (mapping type is not "direct") are returned, making
it easy to identify renumbered or abolished codes across
releases.
map_psgc() has been rewritten with a fully vectorised
algorithm. The crosswalk is pre-split by hop once per call and all codes
are processed simultaneously at each hop using match(),
replacing the previous per-code loop. This yields roughly a 500×
speed-up for large code vectors (e.g. 1 000 codes: 94 s → < 0.2
s).These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
