Combine Two Rules

Usage

combine_rules(x, y, ...)

Arguments

x: (rule) to modify.
y: (rule) rule whose mapping will take precedence over the ones described in x.
...: not used.

Value

a rule.

Note

The order of the mappings in the resulting rule corresponds to the order of the mappings in x followed by the mappings that are only present in y.

Examples

r1 <- rule(
  "first" = c("from ori rule", "FROM ORI RULE"),
  "last" = c(NA, "last"),
  .to_NA = "X",
  .drop = TRUE
)
r2 <- rule(
  "first" = c("F", "f"),
  "second" = c("S", "s"),
  "third" = c("T", "t"),
  .to_NA = "something"
)
combine_rules(r1, r2)
#> Mapping of:
#> first  <-  "F", "f" 
#> last  <-  <NA>, "last" 
#> second  <-  "S", "s" 
#> third  <-  "T", "t" 
#> Convert to <NA>: "something" 
#> Convert to factor: TRUE 
#> Drop unused level: FALSE 
#> NA-replacing level in last position: TRUE
