3 months ago Thank you for the question @yhan818.
So the main difference is the entity you're querying.
- If you're looking for information on the author,
entity = "authors", either of these 2 function calls works because you can query directly using the OpenAlex ID viaidentifieror usingopenalexas a filter for the "authors" entity.
library(openalexR)
author_id <- "a5016874418"
author <- oa_fetch(entity = "authors", identifier = author_id, verbose = TRUE)
#> Requesting url: https://api.openalex.org/authors/a5016874418
author <- oa_fetch(entity = "authors", openalex = author_id, verbose = TRUE)
#> Requesting url: https://api.openalex.org/authors?filter=openalex%3Aa5016874418

- If you're looking for works by this author,
entity = "works", you need to useauthorships.author.idorauthor.idas a filter:
library(openalexR)
author_id <- "a5016874418"
oa_fetch(
entity = "works", author.id = author_id,
publication_year = 2023, verbose = TRUE
)

Hi,
I have the following code:
author_name <- "Bekir Tanriover" author_id <- "a5016874418"
1. working
author<- oa_fetch(entity = "authors", identifier = author_id, verbose = TRUE)
2. Not working "author.id" is not a valid field
author<- oa_fetch(entity = "authors", author.id = author_id, verbose = TRUE)
3. Not working with para "identifier". It works with para "author.id"
work <- oa_fetch(entity = "works",
author.id = author_id,
For documentation at https://docs.ropensci.org/openalexR/reference/oa_fetch.html the parameter of the above shall be "identifier", but the code works one way or another.
Why is that?
