Arguments

query

(character) query string, required

metadata

(logical) Whether to retrieve the full article metadata or only the ID. Default: TRUE

fulltext

(logical) Whether to retrieve full text of the article. Default: FALSE

citations

(logical) Whether to retrieve citations found in the article. Default: FALSE

similar

(logical) Whether to retrieve a list of similar articles. Default: FALSE. Because the similar articles are calculated on demand, setting this parameter to true might slightly slow down the response time

duplicate

(logical) Whether to retrieve a list of CORE IDs of different versions of the article. Default: FALSE

urls

(logical) Whether to retrieve a list of URLs from which the article can be downloaded. This can include links to PDFs as well as HTML pages. Default: FALSE

faithfulMetadata

(logical) Returns the records raw XML metadata from the original repository. Default: FALSE

page

(character) page number (default: 1), optional

limit

(character) records to return (default: 10, minimum: 10, maximum: 100), optional

key

A CORE API key. Get one at https://core.ac.uk/api-keys/register. Once you have the key, you can pass it into this parameter, or as a much better option, store your key as an environment variable with the name CORE_KEY or an R option as core_key. See ?Startup for how to work with env vars and R options

parse

(logical) Whether to parse to list (FALSE) or data.frame (TRUE). Default: TRUE

...

Curl options passed to HttpClient

Details

core_articles_search does the HTTP request and parses, while core_articles_search_ just does the HTTP request, gives back JSON as a character string
