ifelse

Vectorized If-Else

Evaluates a condition and returns values from true_val or false_val depending on the condition. Supports missing value handling via the missing argument.

Parameters

• condition (Bool | Vector[Bool]): The logical condition to evaluate. Accepts a scalar or a vector.

• true_val (Any): Expected return value when condition is true.

• false_val (Any): Expected return value when condition is false.

• missing (Any): (Optional) Value to return when condition is NA.

• out_type (String): (Optional) Explicit output type casting.

Returns

A scalar when condition is scalar, otherwise a vector aligned to condition.

Examples

ifelse([true, false, NA], "Yes", "No", missing = "Unknown")
