(is.na(sub_affiliation[[1]])) { : the condition has length > 1 Error

[Fulup]

Dear OpenalexR support team, Please could you advise on improving this R script using openalexR which was working last week but is now reporting an error. I have reinstalled the openalexR package today.

I have a dataframe called _UoAresearchers imported from a csv file containing Openalex IDs.

# create a dataframe the size of the number of researchers in the input file
data <- numeric(length(UoA_researchers$OpenalexID))

# populate the dataframe with the results of our Openalex searches
for(i in seq_along(UoA_researchers))
{
# For Loop to run repeated searches of Openalex
 data <- oa_fetch(
  identifier = UoA_researchers$OpenalexID,
  entity     = "authors",
  mailto     = "my_email@example.com", # politeness, please use your own email address
  verbose    = FALSE
   )
 }
# let's have a look at the retrieved data
head(data)

# add some context to each line
data <- data |>
  select(display_name, id, orcid) |>
  mutate(uoa = "20", unit = "Social Work and Social Policy")

# and write the results to a file. Change the filename to reflect the UoA.
write_csv(data, "openalex_researchers_UoA20.csv")
=====
However, I am getting an error message:
Error in if (is.na(sub_affiliation[[1]])) { :
the condition has length > 1
5.
authors2df(data, verbose)
4.
FUN(X[[i]], ...)

lapply(final_res, oa2df, entity = entity, options = options,

Thank you for reporting @Fulup! Unfortunately, without the actually OpenalexID, I can't reproduce the issue. Could you give us at least one id that gives you this error? Thanks!

[Fulup]

Hi, Thanks for your interest in this issue. Please try this OpenalexID: A5049085191

Here are the full files I am trying to work with. I hope that help give a better context.

@Fulup I don't think you can share the full file via email to show on GitHub. I tried your example openalex id and it's working for me:

library(openalexR)
author <- oa_fetch(
  identifier = "A5049085191",
  verbose    = TRUE
)
#> Requesting url: https://api.openalex.org/authors/A5049085191

Hi all,

I am just running into the same issue. Weirdly enough, it happens when I try to reproduce my old code that worked before. For the sake of reproducibility, I am loading openalexR like this:

library(groundhog)

groundhog.library("openalexR", date = "2023-12-01")

The error persists even when just loading using library(openalexR).

Here is what I am doing:

oa_fetch(entity = "author", search = "John Smith")

It returns this: Error in if (is.na(sub_affiliation[[1]])) { : the condition has length > 1

The problem is obviously in the conversion to dataframe, since this works: oa_fetch(entity = "author", search = "John Smith", output = "list")

But this does not: oa_fetch(entity = "author", search = "John Smith", output = "dataframe")

Do you have any advice on how to tackle this? Thanks!

[trangdata]

Hi @amacanovic could you try re-installing openalexR, please?

[yjunechoe]

Maybe this deserves a separate discussion, but IMO it doesn't make much sense (at least on account of reproducibility) to version lock {openalexR} if you're not also version controlling the OpenAlex API and their database snapshot.

To @trangdata 's point, I think {openalexR} should simply be kept updated to the most recent version whenever it is used for real-time queries to the OpenAlex API. I can also confirm that the oa_fetch() code works on the dev version of the package :)

[rkrug]

@yjunechoe I agree - that should be a separate discussion. Especially, as there is the same (or very similar) point in https://github.com/ropensci/openalexR/issues/253#issuecomment-2156087336 . Would it be possible to have a discussion, as this not really belonged in the Issues? I will be happy to chime in when there is one starting point for the discussion, as I think this touches many points, going from expectations, over different usage pattern, to directions the revision if openalexR could take.

[amacanovic]

Hi all,

Reinstalling indeed solves this. Thanks for pointing this all out; I will add a note on this in my code repo.
