Detect decoy / reverse-database identifiers

Flags identifiers that look like decoy (reversed) database entries. Built-in anchored default prefixes are always considered, unioned with an optional configured pattern. An empty string or NULL pattern uses the defaults only.

Usage

is_decoy(ids, pattern = NULL)

Arguments

ids

character vector of (prefixed) identifiers

pattern

optional additional decoy regex, unioned with the defaults

Value

logical vector, TRUE where an id looks like a decoy
