Creates new variables with different values based on a set of logical expressions.
code [[#]] [[$]] var [[default defval]] with
val_1 for expression_1,
val_2 for expression_2,
val_n for expression_n
- var (literal) – the new variable name.
- defval (scalar) – the default value if none of the expressions are TRUE.
- val (scalar) – value to be used if corresponding expression is TRUE.
- expression (scalar) – logical scalar-returning expression that returns nonzero TRUE or zero FALSE
code agecat default 5 with 1 for age < 21, 2 for age >= 21 and age < 35, 3 for age >= 35 and age < 50, 4 for age >= 50 and age < 65;
code $ sex with "MALE" for gender == 1, "FEMALE" for gender == 0;
If ‘$’ is specified, the new variable will be considered a character variable. If ‘#’ or nothing is specified, the new variable will be considered numeric.
The logical expressions must be mutually exclusive, i.e., only one may return TRUE for a given row (observation).
Any variables referenced must already exist, either as elements of the source dataset, as externs, or as the result of a previous make, vector, or code statement.
If no default value is specified, 999 is used.
