A .jsonl file (newline separated JSON) created from open data available at [ftp://ftp.libris.kb.se/pub/spa/swepub-deduplicated-2019-12-29.zip] is used with the R package arrow (installed from CRAN) using the following statement:

> arrow::read_json_arrow("~/.config/swepub/head.jsonl")

It crashes RStudio with no error message. At the R prompt, the error message is:

Error in Table__to_dataframe(x, use_threads = option_use_threads()) : 
 SET_VECTOR_ELT() can only be applied to a 'list', not a 'integer'

The file "head.jsonl" above was created from the extracted zip's .jsonl file with the *nix "head" command. It can be parsed with jsonlite and tidyjson.
