 | SeriesExtensionsFillMissingK, T Method (SeriesK, T, Direction) |
Fill missing values in the series with the nearest available value
(using the specified direction). The default direction is `Direction.Backward`.
Note that the series may still contain missing values after call to this
function. This operation can only be used on ordered series.
## Example
let sample = Series.ofValues [ Double.NaN; 1.0; Double.NaN; 3.0 ]
// Returns a series consisting of [1; 1; 3; 3]
sample.FillMissing(Direction.Backward)
// Returns a series consisting of [<missing>; 1; 1; 3]
sample.FillMissing(Direction.Forward)
## Parameters
- `direction` - Specifies the direction used when searching for
the nearest available value. `Backward` means that we want to
look for the first value with a smaller key while `Forward` searches
for the nearest greater key.
