Spatial data migrated from sp to sf. The yearly Continuum of Care boundary objects (coc2007–coc2024) are now single national sf objects (one row per CoC) instead of 51-element lists of SpatialPolygonsDataFrames, and sp_homeless is now an sf object. Imports is now sf rather than sp.
New data
Extended the HUD Point-in-Time count series (hud2016–hud2024) and CoC boundary series (coc2016–coc2024) through 2024.
Added a Census-to-CoC crosswalk family: tract_coc20XX (hard tract-to-CoC assignment by tract centroid) and tract_coc_wt20XX (area- and population-weighted tract/county-to-CoC overlap shares), adapted from Tom Byrne’s crosswalk procedure.
Added hud2025_prelim, a clearly flagged preliminary 2025 estimate derived from Community Solutions’ population-weighted ratio estimator. These figures have not undergone HUD’s quality-assurance process and are not directly comparable to the official hud20XX series.
Other changes
American Community Survey covariates are now built with tidycensus (the former American FactFinder source is retired).
Added cross-sectional data-integrity tests and three introductory vignettes centered on California and Washington.
Documentation, DESCRIPTION, and metadata updated for CRAN compliance.
