Just using `arrow::read_parquet()` in R. Everything is regular, nothing fancy. Anything else I need to provide?
arrow_8.0.0
They were SAS datasets. I used `haven::read_sas()` to load them into memory and then used `arrow::write_parquet()` to write them into disk for future use.
I am not sure about the first question, but there are 80 columns or so.
Seems like so.
