我有一个如下所示的数据集:
Category Amount
SALES
Alcohol Sales $33,436
Cigarette Sales 78,953
TOTAL SALES 645,860
Alcohol COS 22,313
Cigarette COS 59,098
Grocery CC Fees 1,956
Roller Grill Spoilage 432
TOTAL COST OF SALES 55,555
我想在“TOTAL SALES”和“TASAL COST OF SLAES”之间的所有内容中添加一个标志,因此输出将是这样的:
Category Amount Flag
SALES
Alcohol Sales $33,436
Cigarette Sales 78,953
TOTAL SALES 645,860
Alcohol COS 22,313 1
Cigarette COS 59,098 1
Grocery CC Fees 1,956 1
Roller Grill Spoilage 432 1
TOTAL COST OF SALES 55,555
我应该怎么做?
答案 0 :(得分:1)
您可以创建一个新的变量flag
,在观察结果中保留其值,并在适当的时间设置/取消设置。类似的东西:
data sales2;
set sales;
length flag $1;
retain flag ' ';
if category = 'TOTAL COST OF SALES' then
flag = ' ';
output;
if category = 'TOTAL SALES' then
flag = '1';
run;
