Usage

core_articles_history(id, page = 1, limit = 10, key = NULL, parse = TRUE, ...)

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

...

Curl options passed to HttpClient

Value

core_articles_history_ returns a JSON string on success. core_articles_history returns a list (equal to id length) where each element is a list of length two with elements for data and status of the request; on failure the data slot is NULL.

Details

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