             Summary: [R] ChunkedArray$cast() combine multiple arrays into one
                 Key: ARROW-15828
                 URL: https://issues.apache.org/jira/browse/ARROW-15828

          Issue Type: Bug
          Components: R
    Affects Versions: 7.0.0
            Reporter: SHIMA Tatsuya


It appears that if I try to cast to int or float, the array will be one.
