> I was reading files that I created on the same laptop, same R version and Arrow version 7.0.0. The error I get when reading int32-type columns is
> {code:java}
> > source("~/github/un_escap/hs12-historic-series/00-create-historic-series.R")
> 2012
> Error in `handle_csv_read_error()`:
> ! NotImplemented: Function 'equal' has no kernel matching input types (array[int32], scalar[string])
> Run `rlang::last_error()` to see where the error occurred. {code}
> Here's a minimal example of the code that caused this
> {code:java}
> library(arrow)
> library(dplyr)
> d <- open_dataset("aggregate_level=0",
>                   partitioning = c("trade_flow", "year", "reporter_iso"))
> d %>%
>   select(reporter, reporter_code, reporter_iso) %>%
>   collect() {code}
> After going back to Arrow R package v6.0.2, it worked. Here "reporter_code" is numeric.
> I've attached a zip with the data.
