List the BRFSS survey years available for download

Reads the data manifest that accompanies the hosted parquet releases and returns the survey years currently published. The manifest is cached locally and refreshed at most once a day; pass refresh = TRUE to force a new download.

The three arguments cover the three questions in order. download decides whether the network may be touched at all, refresh forces a download that the daily cadence would otherwise skip, and quiet silences the housekeeping notes. download = FALSE therefore wins over refresh = TRUE: the strictly offline promise is the stronger one, and the skipped refresh is reported rather than assumed.

Usage

brfss_years(refresh = FALSE, download = TRUE, quiet = FALSE)

Arguments

refresh: If TRUE, re-download the manifest even if a fresh cached copy exists. Ignored under download = FALSE.
download: If FALSE, only the cached (or bundled) manifest is read and the network is never touched.
quiet: If TRUE, suppress the housekeeping notes about which copy was used (brfssdata_manifest_note). The returned years are the same either way.

Value

An integer vector of available survey years. If the manifest cannot be refreshed, or the cached copy is unreadable, a message notes the fallback (cached or bundled copy) that was used instead.

Examples

if (FALSE) { # interactive()
brfss_years()
}
