Get articles

core_articles(
  id,
  metadata = TRUE,
  fulltext = FALSE,
  citations = FALSE,
  similar = FALSE,
  duplicate = FALSE,
  urls = FALSE,
  extractedUrls = FALSE,
  faithfulMetadata = FALSE,
  key = NULL,
  method = "GET",
  parse = TRUE,
  ...
)

core_articles_(
  id,
  metadata = TRUE,
  fulltext = FALSE,
  citations = FALSE,
  similar = FALSE,
  duplicate = FALSE,
  urls = FALSE,
  extractedUrls = FALSE,
  faithfulMetadata = FALSE,
  key = NULL,
  method = "GET",
  ...
)

`id`	(integer) CORE ID of the article that needs to be fetched. Required
`metadata`	Whether to retrieve the full article metadata or only the ID. Default: `TRUE`
`fulltext`	Whether to retrieve full text of the article. Default: `FALSE`
`citations`	Whether to retrieve citations found in the article. Default: `FALSE`
`similar`	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 query
`duplicate`	Whether to retrieve a list of CORE IDs of different versions of the article. Default: `FALSE`
`urls`	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`
`extractedUrls`	Whether to retrieve a list of URLs which were extracted from the article fulltext. Default: `FALSE`. This parameter is not available in CORE API v2.0 beta
`faithfulMetadata`	Whether to retrieve the raw XML metadata of the article. Default: `FALSE`
`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
`method`	(character) one of 'GET' (default) or 'POST'
`parse`	(logical) Whether to parse to list (`FALSE`) or data.frame (`TRUE`). Default: `TRUE`
`...`	Curl options passed to `HttpClient`

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

These functions take one article ID at a time. Use lapply/loops/etc for many ids

## you can use method="GET" with lapply or similar
res <- lapply(ids, core_articles)
vapply(res, "[[", "", c("data", "datePublished"))

## or use method="POST" passing all at once
res <- core_articles(ids, method = "POST")
head(res$data)
res$data$authors

# just http request, get text back
core_articles_(id = '21132995')
## POST, can pass many at once
core_articles_(id = ids, method = "POST")
