SeriesModule.resampleUniformInto(K1, K2, V, a) Method

Resample the series based on equivalence class on the keys and also generate values for all keys of the target space that are between the minimal and maximal key of the specified series (e.g. generate value for all days in the range covered by the series). A specified function `keyProj` is used to project keys to another space and `nextKey` is used to generate all keys in the range. The chunk is then aggregated using `f`. When there are no values for a (generated) key, then the function behaves according to `fillMode`. It can look at the greatest value of previous chunk or smallest value of the next chunk, or it produces an empty series. ## Parameters - `series` - An input series to be resampled - `fillMode` - When set to `Lookup.ExactOrSmaller` or `Lookup.ExactOrGreater`, the function searches for a nearest available observation in an neighboring chunk. Otherwise, the function `f` is called with an empty series as an argument. Values `Lookup.Smaller` and `Lookup.Greater` are not supported. - `keyProj` - A function that transforms keys from original space to a new space (which is then used for grouping based on equivalence) - `nextKey` - A function that gets the next key in the transformed space - `f` - A function that is used to collapse a generated chunk into a single value. The function may be called on empty series when `fillMode` is `Lookup.Exact`. ## Remarks This operation is only supported on ordered series. The method throws `InvalidOperationException` when the series is not ordered. [category:Sampling, resampling and advanced lookup]
