arthurgailes opened a new issue, #39660: URL: https://github.com/apache/arrow/issues/39660
### Describe the bug, including details regarding any error messages, version, and platform. Arrow does not correctly interpret some partition values as character columns, resulting in data loss. ``` r library(arrow) library(dplyr) # character col with leading zero mtcars2 <- mutate(mtcars, test = paste0(0, mtcars$carb)) |> as_tibble() tmp <- tempfile() write_dataset(mtcars2, tmp, partitioning = "test") mtcars3 <- open_dataset(tmp) |> collect() unique(mtcars2$test) #> [1] "04" "01" "02" "03" "06" "08" unique(mtcars3$test) #> [1] 1 2 3 4 6 8 ``` <sup>Created on 2024-01-17 with [reprex v2.0.2](https://reprex.tidyverse.org)</sup> ### Component(s) R -- This is an automated message from the Apache Git Service.
