[GitHub] [arrow-nanoarrow] paleolimbot opened a new issue, #218: [R] Add extension type support
paleolimbot opened a new issue, #218:
URL: https://github.com/apache/arrow-nanoarrow/issues/218
Originally noted in #66, converting extension types currently warns and converts the storage type. For extension types like geoarrow, we will need some S3 method or registration to customize Arrow -> R when there is an extension type. `arrow::vctrs_extension_array()` is probably a good place to start.
``` r
library(nanoarrow)
library(arrow, warn.conflicts = FALSE)
#> Some features are not enabled in this build of Arrow. Run `arrow_info()` for more information.
ext_array <- vctrs_extension_array(1:10)
na_array <- as_nanoarrow_array(ext_array)
convert_array(na_array)
#> Warning in convert_array.default(na_array): Converting unknown extension
#> arrow.r.vctrs{int32} as storage type
#> [1] 1 2 3 4 5 6 7 8 9 10
```
