Error in (function (..., row.names = NULL, check.rows = FALSE, check.names = TRUE, : arguments imply differing number of rows: 1, 0

[jwbesse]

Dear openalexR team,

I'm running the following code to get papers matching certain search strings:

works_title <- oa_fetch(
  entity = "works",
  per_page = 200, 
  paging = "cursor", 
  title.search = c("Neurotechnology", 
                   "Neuroinformatics"),

  from_publication_date = "2021-01-01",
  to_publication_date = "2023-12-31",

  cited_by_count = ">1",
  options = list(sort = "cited_by_count:desc"),
  verbose = TRUE
)

However, I'm getting the following error:

Error in (function (..., row.names = NULL, check.rows = FALSE, check.names = TRUE,  : 
  arguments imply differing number of rows: 1, 0

Is there anything you can tell me which might help solve the issue?

I was hitting the same problem. I updated to the github version of the package and that solved the issue for me.

remotes::install_github("ropensci/openalexR")

Using your example:

library(openalexR)
#> Thank you for using openalexR!
#> To acknowledge our work, please cite the package by calling `citation("openalexR")`.
#> To suppress this message, add `openalexR.message = suppressed` to your .Renviron file.
works_title <- oa_fetch(
  entity = "works",
  per_page = 200, 
  paging = "cursor", 
  title.search = c("Neurotechnology", 
                   "Neuroinformatics"),

  from_publication_date = "2021-01-01",
  to_publication_date = "2023-12-31",

  cited_by_count = ">1",
  options = list(sort = "cited_by_count:desc"),
  verbose = TRUE
)

Thank you @DrMattG! 🙏🏽 I got the same result!

@jwbesse I believe this is now fixed with #233. Please let me know if you still encounter the error after installing the github version of the package.

remotes::install_github("ropensci/openalexR")

Hello, I am encountering this same original problem and I have tried the above proposed solution of installing the github version of the package.

@Scientometrics101 Could you let us know which version of the package you're using?

I have the same problem with the package version 1.2.3.

it would be great to see a solution, thanks for your efforts!

[trangdata]

@andreaspacher I'm sorry that you're still getting an error. Could you try re-installing one more time? v1.3.0 should work now.

remotes::install_github("ropensci/openalexR")
packageVersion("openalexR")
#> [1] '1.3.0'
