retractcheck (version 1.0.0)

retractcheck: retractcheck: Retraction scanner

Description

Using 'Digital Object Identifiers', check for retracted (or otherwise updated) articles using 'Open Retractions' <http://openretractions.com>.

Using the http://openretractions.com API, this function checks whether a DOI has been updated, when that update was made, and what type of update was made.

Usage

retractcheck(dois, database = "or", return = "unique")

Arguments

dois

Character. Vector of containing only DOIs

database

Character. Abbreviation of the databases to search (or for openretractions.com). # #' and rw for # #' retractiondatabase.com). Note that in the absence of an API, # #' searching retractiondatabase.com is rather slow.

return

Character. If all, all DOIs are queried and all results are returned; if unique, the DOIs are queried in the order specified until either a correction or retraction notice is found or all databases have been queried.

Value

retractcheck data.frame

# NOT RUN {

  retractcheck(c('10.1002/job.1787',
