In ropensci/rmetadata: Work with many Scholarly Metadata APIs in R.

Count OAI-PMH identifiers for a data provider.

Description

Count identifiers for the data sources from the OAI-PMH list, and others not on that list, including PMC, DataCite, Hindawi Journals, Dryad, and Pensoft Journals.

Usage

count_identifiers(provider = NULL, metadataPrefix = "oai_dc",
  fuzzy = FALSE, useurl = FALSE, seconds = 3)

Arguments

provider	The metadata provider.
metadataPrefix	Specifies the metadata format that the records will be returned in.
fuzzy	Do fuzzy search or not (default FALSE). Fuzzy uses agrep.
useurl	Setting to TRUE allows you to just provide the metadata provider name, and any matches found the function will just use the url to query their OAI-PMH API.
seconds	Number of seconds by which to timeout an API call to one of the data providers.
