Convert PMID to DOI using PubMed API

Source: R/mod_references_fct_crossref.R
pmid_to_doi.Rd

Attempts to convert a PubMed ID to a DOI by querying the PubMed API. This is necessary because Crossref doesn't directly support PMID lookup.

Usage

pmid_to_doi(pmid)

Arguments

pmid

Character string containing PMID

Value

List with components:

  • success: Logical indicating whether conversion succeeded

  • doi: DOI string (if success = TRUE) or NULL

  • message: Status message for user feedback

Details

Uses the PubMed E-utilities API to fetch article information and extract DOI. Requires internet connection. May fail if PubMed is unavailable or if the article doesn't have a DOI registered.

Examples

if (FALSE) { # \dontrun{
  result <- pmid_to_doi("12345678")
  result$doi
} # }
