Get unique values in a ChunkedArray
Required methods
fn unique(&self) -> Result<ChunkedArray<T>>
fn unique(&self) -> Result<ChunkedArray<T>>
Get unique values of a ChunkedArray
fn arg_unique(&self) -> Result<IdxCa>
fn arg_unique(&self) -> Result<IdxCa>
Get first index of the unique values in a ChunkedArray.
This Vec is sorted.
Provided methods
fn is_unique(&self) -> Result<BooleanChunked>
fn is_unique(&self) -> Result<BooleanChunked>
Get a mask of all the unique values.
fn is_duplicated(&self) -> Result<BooleanChunked>
fn is_duplicated(&self) -> Result<BooleanChunked>
Get a mask of all the duplicated values.
fn mode(&self) -> Result<ChunkedArray<T>>
fn mode(&self) -> Result<ChunkedArray<T>>
The most occurring value(s). Can return multiple Values
