adjust-interval clj

(adjust-interval dataset
                 index-column-name
                 keys
                 ->new-time-converter
                 new-column-name)

Adjusts the interval of the dataset by adding a new column new-column-name whose values are the result of applying time-converter to the column specified by index-column-name, and then performing a group-by operation on that column and any columns specified by keys.

down-to-nearest clj

(down-to-nearest interval chrono-unit)

(down-to-nearest interval chrono-unit datetime)

slice clj

(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
