Changes in version 0.1.0 (2026-09-29) Initial release. - rais_available() lists every archive published on the PDET/MTE FTP server, with size, modification date and edition (final, partial, legacy). - rais_files() resolves offline which archive holds a state in a year (one file per state up to 2017, regional files from 2018) and rais_ufs() gives the state table behind it. - rais_download() fetches the archives into an idempotent local cache that mirrors the server layout (rais_cache_dir(), rais_cache_list(), rais_cache_clear()). - rais_read() stream-reads a .7z archive, filtering by state and selecting columns chunk by chunk, detecting the file generation (; with decimal comma up to the RAIS 2022, , with decimal point from the RAIS 2023) and mapping both to the same normalized column names; rais_fetch() combines download and read for several years. - rais_stock() consolidates the stock on 31 December, admissions, separations and December payroll by any grouping. - rais_layout() documents the columns of the employment and establishment files, with the two header spellings of each. - Sample archives in inst/extdata (both generations, employment and establishments, plus a pre-2018 state file) allow every reading function to be tried offline.
