tablecloth.time.api.slice
sliceclj
(slice dataset from to)(slice dataset from to {:keys [result-type] :or {result-type :as-dataset}})Returns a subset of dataset's rows (or row indexes) as specified by from and to, inclusively.
from and to are either strings or datetime type literals (e.g. #time/local-date "1970-01-01").
The dataset must have been indexed, and the time unit of the index must match the unit of time
by which you are attempting to slice.
Options are:
- result-type - return results as dataset (
:as-dataset, default) or a row of indexes (:as-indexes).
Example data:
| :A | :B |
|---|---|
| 1970 | 0 |
| 1971 | 1 |
| 1972 | 2 |
| 1973 | 3 |
Example:
(-> data (index-by :A) (slice "1972" "1973"))
;; => _unnamed [2 2]:
| :A | :B |
|---|---|
| 1972 | 2 |
| 1973 | 3 |
