transpose method

DataFrame transpose({
  1. bool includeHeader = false,
  2. String headerName = 'column',
  3. Iterable<String>? columnNames,
})

Transposes rows and columns. This is an expensive operation.

Implementation

DataFrame transpose({
  bool includeHeader = false,
  String headerName = 'column',
  Iterable<String>? columnNames,
}) {
  if (includeHeader) _validateName(headerName, 'headerName');
  final names = columnNames == null
      ? null
      : _validatedNames(columnNames, 'columnNames');
  return _frameInput('frameTranspose', {
    'includeHeader': includeHeader,
    'headerName': headerName,
    if (names != null) 'columnNames': names,
  });
}
