### Describe the bug, including details regarding any error messages,
version, and platform.
The docs say
```
write_dataset package:arrow R Documentation
Write a dataset
Description:
This function allows you to write a dataset. By writing to more
efficient binary storage formats, and by specifying relevant
partitioning, you can make it much faster to read and query.
Usage:
write_dataset(
dataset,
path,
format = c("parquet", "feather", "arrow", "ipc", "csv", "tsv", "txt",
"text"),
partitioning = dplyr::group_vars(dataset),
basename_template = paste0("part-{i}.", as.character(format)),
hive_style = TRUE,
existing_data_behavior = c("overwrite", "error", "delete_matching"),
max_partitions = 1024L,
max_open_files = 900L,
max_rows_per_file = 0L,
min_rows_per_group = 0L,
max_rows_per_group = bitwShiftL(1, 20),
...
)
Value:
The input ‘dataset’, invisibly
```
but when I write datasets, I get nothing in return:
```r
res <- arrow::write_dataset(mtcars, "mt")
res
# NULL
```
On Ubuntu-23.10, R-4-3.2, arrow_15.0.1.
