             Summary: [R] Better document the CSV read/parse/convert options we can use with open_dataset()
                 Key: ARROW-18354
                 URL: https://issues.apache.org/jira/browse/ARROW-18354
             Project: Apache Arrow
          Issue Type: Sub-task
          Components: R
            Reporter: Nicola Crane


When a user opens a CSV dataset using open_dataset, they can take advantage of a lot of different options which can be specified via {{CsvReadOptions$create()}} etc.

However, as they are passed in via the ellipses ({{...}}) argument, it's not particularly clear to users which arguments are supported or not.  They are not documented in the {{open_dataset()}} docs, and further confused (see the code for {{CsvFileFormat$create()}} by the fact that we support a mix of Arrow and readr parameters.

We should better document the arguments we do support.
