Combine groups to make a list of all possible verification groups

This function is intended to define all possible group combinations for use in verification functions such as det_verify. When time_groups are given, the function ensures that they appear in every group.

Usage

make_verif_groups(time_groups, groups)

Arguments

time_groups

Groups that could be used as a time axis in a plot. Can be any combination of "lead_time", "valid_dttm" and "valid_hour".

groups

Other group columns to use in a verification.

Value

A list of group combinations

Examples

make_verif_groups("lead_time", c("fcst_cycle", "station_group"))
