identifiers function

Get identifiers

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.

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.

Returns

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

Examples

## Not run:

# Result of call to works()
x <- works(orcid_id("0000-0001-8607-8025"))
# doi by default
identifiers(x)
# orcids
identifiers(x, "orcid")
# pmid
identifiers(x, "pmid")
# pmc 
identifiers(x, "pmc") 
# other_id
identifiers(x, "other_id")

# Result of call to orcid_id()
x <- orcid_id(orcid = "0000-0002-9341-7985")
identifiers(x, "doi")
identifiers(x, "eid")

# Result of call to orcid()
x <- orcid(query="carl+boettiger")
identifiers(x)

# Result of call to orcid_doi()
x <- orcid_doi(dois="10.1087/20120404", fuzzy=TRUE)
identifiers(x)
## End(Not run)
