In fb4package: 'Fish Bioenergetics 4.0' Model Implementation with High-Performance 'TMB' Backend

Check Numeric Value

Description

Fast validation of numeric values with basic range checking. Simplified utility function for common validation needs.

Usage

check_numeric_value(value, name, min_val = -Inf, max_val = Inf)

Arguments

value	Value to validate
name	Parameter name for error messages
min_val	Minimum allowed value (default -Inf)
max_val	Maximum allowed value (default Inf)

Details

Performs essential validations:

• Not NULL

• Numeric type

• Finite values (no NA, NaN, Inf)

• Within specified range

Value

The original value (numeric, same length as input), returned unchanged when all checks pass. Throws an error if value is NULL, non-numeric, contains non-finite elements (NA, NaN, Inf), or falls outside [min_val, max_val].

Examples

check_numeric_value(5, "weight")
try(check_numeric_value(-1, "weight", min_val = 0))
try(check_numeric_value(NA, "weight"))
