head method

DataFrame head({
  1. int nRows = 5,
  2. bool asView = true,
})

Returns a DataFrame consisting of the first nRows rows or less if the instance holds less.

asView set to true leads to a view of the current data being returned, otherwise a copy will be returned.

Implementation

DataFrame head({int nRows = 5, bool asView = true}) => _viewOrCopy(
    _trackedColumnNames.l, getRange(0, min(nRows, length)).toList(), asView);
