[GitHub] [arrow-nanoarrow] paleolimbot opened a new issue, #220: [R] Implement conversions for dictionary encoding

paleolimbot opened a new issue, #220:
URL: https://github.com/apache/arrow-nanoarrow/issues/220

   Currently this just doesn't work. Factors are converted to dictionary encoding by default, so this is potentially problematic.
   
   ``` r
   library(nanoarrow)
   library(arrow, warn.conflicts = FALSE)
   #> Some features are not enabled in this build of Arrow. Run `arrow_info()` for more information.
   
   dictionary_array <- as_nanoarrow_array(factor(letters[1:5]))
   convert_array(dictionary_array)
   #> Error in convert_array.default(dictionary_array): Can't infer R vector type for array <dictionary(int32)<string>>
   ```
