COCI: OpenCitations Index of Crossref open DOI-to-DOI references
Description
AFAICT this API is a REST wrapper around the SPARQL service
Usage
oc_coci_refs(doi, exclude = NULL, filter = NULL, sort = NULL, ...)
oc_coci_cites(doi, exclude = NULL, filter = NULL, sort = NULL, ...)
oc_coci_meta(doi, exclude = NULL, filter = NULL, sort = NULL, ...)
oc_coci_citation(oci, ...)
Arguments
doi |
(character) one or more Digital Object Identifiers (DOIs) |
exclude |
(character) a field_name; all the rows that have an empty value in the field_name specified are removed from the result set |
filter |
|
sort |
|
... |
curl options passed on to crul::verb-GET |
oci |
(character) one or more Open Citation Identifiers (OCIs) |
Value
data.frame, see http://opencitations.net/index/coci/api/v1 for explanation of the resulting columns

Methods for getting IDs from other IDs
Description
Methods for getting IDs from other IDs
Usage
oc_doi2ids(id, ...)
oc_pmid2ids(id, ...)
oc_pmcid2ids(id, ...)
Arguments
id |
One or more digital object identifiers (DOI), PMID, or PMCID, depending on the function |
... |
curl options passed on to crul::verb-GET |
Value
data.frame, with four columns:
doi: digital object identifier
pmid: pubmed identifier
pmcid: pubmed central identifier
paper: open citations corpus url
An empty data.frame (no columns or rows) when no results found
Column order will always be the same; note though that some columns may be missing if, for example, there's no PMID for a DOI search.
Examples
if (oc_lookup_check()) {
try(
oc_doi2ids("10.1097/igc.0000000000000609", timeout_ms=10),
silent = TRUE
)
}
