identifiers {rorcid}

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", ...)

## S3 method for class 'works'
identifiers(x, type = "doi", ...)

## S3 method for class 'list'
identifiers(x, type = "doi", ...)

## S3 method for class 'orcid_id'
identifiers(x, type = "doi", ...)

## S3 method for class 'orcid'
identifiers(x, type = "doi", ...)

## S3 method for class 'orcid_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. This parameter is ignored for classes orcid and orcid_doi both of which would go down a rabbit hole of getting works for all ORCIDs which could take a while.

...

Ignored.

Value

(character) vector of identifiers, or NULL if none found
