Download or update a local snapshot of the retraction corpus

The first call downloads the full corpus (sliced by retraction year to respect the export endpoint's row cap and rate limit). Later calls are incremental by default: only recent years are re-fetched and merged into the existing snapshot by record id, so new retractions are added without re-downloading everything. Use force = TRUE for a complete refresh.

Usage

retraction_sync(force = FALSE, incremental = TRUE, quiet = FALSE)

Arguments

force

Re-download the entire corpus, replacing any existing snapshot.

incremental

When a snapshot exists, fetch only recent years and merge (default). Ignored when force = TRUE or no snapshot exists.

quiet

Suppress progress messages.

Value

Invisibly, the snapshot data frame.

Details

Once a snapshot exists, pass offline = TRUE to any check_*() function to match locally without the network.

Examples

if (FALSE) { # \dontrun{
retraction_sync()                 # first run: full download
retraction_sync()                 # later: incremental update
retraction_sync(force = TRUE)     # occasional full refresh
check_bib("refs.bib", offline = TRUE)
} # }
