Register how a parameter should be recast — geo_register

Records the rule (and optionally the weight) to use for a named value column, so callers of geo_recast() need not repeat it. Downstream packages can register their own parameter maps at load time.

Usage

geo_register_rule(param, rule, weight = NULL)

Arguments

param: Name of the value column.
rule: One of GEO_RULES.
weight: Optional weight column name used by sum (down) and weighted_mean (up). NULL means the Geoscale's default weight.

Value

Invisibly, the registered entry.

Examples

geo_register_rule("capacity", "sum")
geo_register_rule("eff", "weighted_mean", weight = "pop")
geo_get_rule("eff")
#> $rule
#> [1] "weighted_mean"
#> 
#> $weight
#> [1] "pop"
#>
