Re: [I] [R] `col_types` ignored when `convert_options` specified [arrow]

thisisnic commented on issue #48144:
URL: https://github.com/apache/arrow/issues/48144#issuecomment-3543346438

   My best guess is that the `col_types` argument in `csv_covert_options()` is overriding the `col_types` argument to `open_delim_dataset()`.  Does this work as a temporary workaround?
   
   ```
   df <- open_delim_dataset(
     "data-raw/test.csv",
     delim = ";",
     convert_options = arrow::csv_convert_options(decimal_point = ",", col_types = schema(a = string()))
   )
   ```
