scopus_search returns $`author-count`$`$` incremented by 1

dkremmydas commented 5 years ago

An example: for eid="2-s2.0-85054194688" author count shall be 4 while 5 is returned

The code to retrieve the record item = scopus_search(query = paste0("eid(2-s2.0-85054194688)"), view = "COMPLETE", verbose = T)

item$entries[[1]]$author-count

That's something you must take up with Scopus itself. I agree that # is off. I would use length(item$entries[[1]]$author) as a better indicator.

Update - this has been "fixed" per Elsevier, but that's true.

Here is the same command:

> item = scopus_search(query = paste0("eid(2-s2.0-85054194688)"), view = "COMPLETE", verbose = TRUE)

The query list is: 
list(query = "eid(2-s2.0-85054194688)", count = 25, start = 0, 
    view = "COMPLETE")
$query
[1] "eid(2-s2.0-85054194688)"

$count
[1] 25

$start
[1] 0

$view
[1] "COMPLETE"

Response [https://api.elsevier.com/content/search/scopus?query=eid%282-s2.0-85054194688%29&count=25&start=0&view=COMPLETE]

Total Entries are 1
Number of Output Entries are 1

Warning message:
In scopus_search(query = paste0("eid(2-s2.0-85054194688)"), view = "COMPLETE",  :
  STANDARD view can have a max count of 200 and COMPLETE 25

with the same output:

> item$entries[[1]]$`author-count`

$`@limit`
[1] "100"

$`$`
[1] "5"

now the number of authors agree:

> length(item$entries[[1]]$author)

[1] 5

but one is actually duplicated:

> length(unique(item$entries[[1]]$author))

[1] 4

> all.equal(item$entries[[1]]$author[[3]], item$entries[[1]]$author[[4]])

[1] TRUE
