breaks-extended
Round breaks from the extended Wilkinson search.
Since 0.6.0.
Scores candidate sequences on simplicity, coverage of the data, and how close the tick count lands to n, which is what the automatic breaks already do; call it to ask for a different n. The counterpart of scales::breaks_extended().
Usage
breaks-extended(
n: 5,
)Parameters
| Parameter | Default | Description |
|---|---|---|

5 |
Target number of ticks; the search trades it off against the other criteria, so the result may hold one or two more or fewer. |
Returns
Closure taking the trained values and returning break positions.
Examples
Eight ticks where the default asks for five.
