Creates a sliding window based on distance between keys. A window is started at each input element and ends once the distance between the first and the last key is greater than the specified `distance`. The windows are then returned as a nested series. The key of each window is the key of the first element in the window. ## Parameters - `distance` - The maximal allowed distance between keys of a window. Note that this is an inline function - there must be `-` operator defined between `distance` and the keys of the series. - `series` - The input series to be aggregated.
