Validate fraction values (0-1 range) — validate

Specialized validator for fraction/proportion values.

Usage

validate_fraction(
  value,
  param_name,
  strategy = "strict",
  allow_zero = TRUE,
  allow_one = TRUE
)

Arguments

value: Value(s) to validate
param_name: Parameter name
strategy: Handling strategy
allow_zero: Whether zero is allowed
allow_one: Whether one is allowed

Value

An object of class fb4_validation (see validation_result). valid is TRUE when all values lie within \([0, 1]\) (or the bounds set by allow_zero and allow_one). Out-of-range values are recorded in errors (strategy "strict") or warnings (strategy "warn").
