Records the aggregation rule to use for a named value column, so callers
of recast_calendar() need not repeat it. Downstream packages can register their
own parameter maps at load time. An explicit rule= argument to
recast_calendar() always wins; unregistered columns default to
"weighted_mean".
Arguments
- param
Name of the value column.
- rule
One of
CALENDAR_RULES.
Examples
register_calendar_rule("energy", "sum")
register_calendar_rule("price", "weighted_mean")
get_calendar_rule("energy")
#> $rule
#> [1] "sum"
