Inventory installed TIGER Address Feature files

taf_manifest() reads the local inventory written as county TAF files are installed. Each row represents one installed county-ZIP Parquet file. Set validate = TRUE to verify the manifest schema and every inventoried file, including its storage schema, row count, byte size, and SHA-256 digest.

Usage

taf_manifest(year = as.character(2025:2011), version = "v2", validate = FALSE)

Arguments

year: character, length 1; vintage of TIGER addrfeat (address feature) files
version: character, length 1; major version of the package and taf dataset schema
validate: logical, length one; validate every manifest row and reject missing, untracked, unreadable, or modified Parquet files?

Value

A tibble with one row per installed county-ZIP file and columns county_fips, ZIP, zip3, zip2, n_ranges, size_bytes, sha256, taf_year, taf_version, and installed_at.

Details

The local manifest is distinct from taf_catalog(). The catalog describes every county-ZIP combination available from TIGER, while the manifest records only files installed on the current machine.

Examples

if (FALSE) { # \dontrun{
taf_manifest()
taf_manifest(validate = TRUE)
} # }
