> I'm currently trying to implement functionality in R so that we can open a dataset and then write to a CSV file, but I'm getting a segfault when I run my tests:
>  
> {code:r}
> tbl <- tibble::tibble(
>   dbl = c(1:8, NA, 10) + .1,
>   lgl = sample(c(TRUE, FALSE, NA), 10, replace = TRUE),
>   false = logical(10),
>   chr = letters[c(1:5, NA, 7:10)]
> )
> make_temp_dir <- function() {
>   path <- tempfile()
>   dir.create(path)
>   normalizePath(path, winslash = "/")
> }
> data_dir <- make_temp_dir()
> write_dataset(tbl, data_dir, partitioning = "lgl")
> data_in <- open_dataset(data_dir)
> csv_file <- tempfile()
> tbl_out <- write_csv_arrow(data_in, csv_file)
> {code}
>  
> {code:java}
> Thread 1 "R" received signal SIGSEGV, Segmentation fault.
