assign_seasonality_ids: Assign seasonality grouping IDs

In njhenry/covidemr: Tools for Mapping COVID Excess Mortality

Description

Create a vector that assigns a (zero-indexed) seasonality grouping ID based on other categories in the data. If no categories are assigned, all rows get the same seasonality grouping ID (0). If categories are based on other ID fields, then a group is assigned to every unique combination of values in those fields. For example, if grouings were assigned based on the "age" and "location" fields, and the data contained four age groupings and 10 unique locations, then 20 unique seasonality groupings would be assigned.

Usage

assign_seasonality_ids(input_data, grouping_fields = NULL)

Arguments

input_data	Data.table of the full input dataset. Must contain fields for any grouping categories that are assigned
grouping_fields	[optional, default NULL] character vector listing any fields in the dataset that should be used to create unique seasonality groups

Value

integer vector with the same number of rows as 'input_data' assigning holdout IDs.
