rorcid (version 0.3.0)

identifiers: Get identifiers

Description

This function aims to pluck out just identifiers into a vector for easy use downstream (e.g., use DOIs to fetch article metadata). You can still manually fetch additional data from outputs of functions in this package.

Usage

identifiers(x, type = "doi", ...)
"identifiers"(x, type = "doi", ...)
"identifiers"(x, type = "doi", ...)
"identifiers"(x, type = "doi", ...)
"identifiers"(x, type = "doi", ...)
"identifiers"(x, type = "doi", ...)

Arguments

x

An object of class works, orcid, orcid_id, orcid_doi, or a list that contains any number of the previous objects.

type

(character) One of doi (default), pmid, pmc, eid, other_id, orcid, scopus, researcherid. The orcid's here are for works, not individuals.

...

Ignored.

Value

A vector of identifiers, or NULL if none found
