类似R中的Function,不过这里可以完整将代码存在一个函数里面,下次可以重复调用。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 % macro test; data a2; X=1; run; %mend test; %test; %macro test; 以及 %mend test; 代表着宏程序的开始与结尾,下次调用的话,就直接%test;即可。 不过,要下次开机...
想仿命令行,所以定义了一个类,让一个String 对应一个 function,将两者输入list容器. 类中定义了 QString commandStr; void (MainWindow::*commandFun)(void);一个QString ,一个指向MainWindow类成员函数的指针.但是没想到在类中使用函数指针这么复杂. 一般情况,我们使用函数指针声明和引用都很简单明了.但是在类...
Extracting entity characteristics from multiple data records requires consolidating and/or comparing data elements across records. The SAS RETAIN statement enables such actions.By default data elements created in a data step are set to missing at the beginning of each DATA step iteration. The ...

The primary reason EERAM is available at a lower price point is the use of standard Complementary Metal-oxide-semiconductor (CMOS) and Flash processes. Because these are the highest volume and most widely used processes, they offer the best reliability and lowest cost in ...
In order to systematically explore multiple possible admixture events for the BaTwa from Kafue, we explored a large set of admixture-graphs using thefind_graphsfunction of ADMIXTOOLS 255, with up to four admixture events. The best fit was a graph with three admixture events. For all tested combi...
Amazingly enough the function is RETAIN, but you want to use it with a new variable. data have; input Test $ Result; datalines; A 12.6 A . A . A . A . B 14.9 B . B . B . B . B . ; data want; set have; by test notsorted; retain tempresult; if first.test the...
