Find out which rules are conflicting

Find out for a contradicting rule which rules are conflicting. This helps in determining and assessing conflicts in rule sets. Which of the rules should stay and which should go?

is_contradicted_by(x, rule_name)

Arguments

x

validator object with rules.

rule_name

character with the names of the rules that are causing infeasibility.

Value

character with conflicting rules.

Examples

rules <- validator( x > 0)

is_infeasible(rules)
#> [1] FALSE

rules <- validator( rule1 = x > 0
                  , rule2 = x < 0
                  )

is_infeasible(rules)
#> [1] TRUE

detect_infeasible_rules(rules)
#> [1] "rule1"
make_feasible(rules)
#> Dropping rule(s): "rule1"
#> Object of class 'validator' with 1 elements:
#>  rule2: x < 0
#> Rules are evaluated using locally defined options

# find out the conflict with this rule
is_contradicted_by(rules, "rule1")
#> [1] "rule2"
