> [R] Support auto-inferring list column type
> -------------------------------------------
>
> Key: ARROW-7662
> URL: https://issues.apache.org/jira/browse/ARROW-7662
> Project: Apache Arrow
> Issue Type: Improvement

> {code:r}
> DF = data.frame(a = 1:10)
> DF$b = as.list(DF$a)
> arrow::write_parquet(DF, 'test.parquet')
> # Error in Table__from_dots(dots, schema) : cannot infer type from data
> {code}
> This appears to be supported naturally already in Python:
> {code:python}
> import pandas as pd
> pd.DataFrame({'a': [1, 2, 3], 'b': [[1, 2], [3, 4], [5,
> 6]]}).to_parquet('test.parquet')
> {code}
