sas - 替换 SAS 数据集中的值

Question

我想要一个代码来将列中的数字替换为字符。

例如:0-“否 1-”是。

我尝试使用 if/else 但它不起作用!!!

Data Assign2.Grocery_coup_two;                                                                                                          
Set Assign2.Grocery_coupons;                                                                                                            
If Heath_food_Store = 0                                                                                                                 
then Health_food_Store = "No";                                                                                                          
Else Health_food_Store = "Yes";                                                                                                         
Run;

您的解决方案不起作用，因为您正试图将数字变量转换为字符串变量。解决此问题的一种方法是将数字变量重命名为 _old，然后运行 ​​if-else 语句:

Data Assign2.Grocery_coup_two;                                                                                                          
    Set Assign2.Grocery_coupons (rename = (Health_food_Store = Health_food_Store_old));                                                                                                            
    If Heath_food_Store_old = 0                                                                                                                 
    then Health_food_Store = "No";                                                                                                          
    Else Health_food_Store = "Yes";                                                                                                         
    DROP Health_food_Store_old;
Run;
