In SAS, do loop arrays are made easily to triage and transform the datas with index-based values. It is nothing but a set of variables of the same type that can be performed using the same operation referenced by the DATA keyword. Generally, the variables in the array are represented as ...
【精品】SAS数组array中的循环loop Loop-Do-Loop Around Arrays Wendi L. Wright, Educational Testing Service, Princeton, NJ ABSTRACT Have you ever noticed your data step repeats the same code over and over? And then thought … there must be a better way. Sure, you could use a macro, but ma...
data example; array scores[5] _temporary_ (100 95 90 85 80); do i = 1 to dim(scores); if i <= dim(scores) then do; put 'Score at index ' i ': ' scores[i]; end; end; run; 通过这种方式,可以有效避免行错误数组下标超出范围的问题,确保程序的稳定性和可靠性。
data example_2; x = ‘Minnesota’; y = ‘Columbus’; run; The log presents the following message: /*日志输出如下信息*/ NOTE: The data set WORK.EXAMPLE_2 has 1 observation and 2 variables. 第二个例子展现了数据步的一个迭代过程如何生成5条观测。DO LOOP循环改变了执行的默认顺序。 data exam...

WHY DO WE NEED ARRAYS? The use of arrays may allow us to simplify our processing. We can use arrays to help read and analyze repetitive data with a minimum of coding. An array and a loop can make the program smaller. For example, suppose we have a file where each record contains 24...
Alternatively, it is often convenient to have the vector of probabilities in an array. In this case, you can use theOF operatorto pass the arguments of the array to the RAND function. If you do not need the probabilities in the output data set, you can use the _TEMPORARY_ keyword to ...
Loop over a variable list (varlist): data new(drop= i); set new; array raymond {4} var1 var2 var3 var4; do i = 1 to 4; if raymond{i} = 99 then raymond{i} = . ; end; run; Check out this array example in the SAS programming examples page. foreach i of varlist var1 ...
LAGn is mainly called it as the array name and formed in the separate queue for maintaining the variable in array memory. If the function is compiled the SAS will allocate the memory in each and every data queues for holding the data bytes is 8 and the memory is needed for 8 times ...
