Get metadata for a BED file or BEDset

Get metadata for a BED file or BEDset given its id. Abort if not found or id is not not 32 characters.

bb_metadata(bedbase, id, full = FALSE)

Arguments

bedbase

BEDbase() object

id

integer(1) record or object identifier

full

logical(1) (default FALSE) include full record with stats, files, and metadata

Value

list() metadata
