if-then语句是一种条件语句,用于根据特定条件执行不同的操作。 在SAS中,可以使用%let语句来定义宏变量,并使用if-then语句来设置宏变量的值。下面是一个示例: 代码语言:txt 复制 %let age = 25; %macro check_age; %if &age < 18 %then %do; %put You are underage.; %end; %else %do; %put You...
if代表判断,为真则执行then后面的内容。其中newstat代表新的变量。 用途1:筛选变量 代码语言:javascript 复制 data d1 d2; set sashelp.class; if _n_ le 10 then output d1; else output d2; run; 其中的le 代表小于等于10, 用途2:do强化if的效率 代码语言:javascript 复制 If age>14 then hcm=...

When you use %IF-%THEN/%ELSE and %DO macro statements in open code to conditionally build statements, an error can occur. Here is an example of code that generates an error: data _null_; attrib a length=3 %if 0 %then %do; b length=4 %end; %else %do; c length=5 %end;; ...

SAS must execute each IF statement even if an earlier IF statement was found to be true. To make matters worse, IF statements require a fair bit of processing time. A substantially faster method is to use the IF-THEN- ELSE statement combination. The following DATA step Hands-on Workshops ...
