> Issue Type: Bug
> Components: R

> In R it's not possible to delete the files eventhough the dataframe is
> cleared from the R environment.
>
> write.csv(mtcars, file = "mtcars.csv", quote = FALSE, row.names = FALSE)
> df <- arrow::to_duckdb(arrow::open_dataset("mtcars.csv", format = "csv",
> delimiter = ","))
> df <- df %>% select(c("mpg", "disp", "drat", "wt")) %>% collect()
> ## Do some checks on df.
