Generating a random output from an array

TanV — Tue, 02 Jul 2019 10:19:58 GMT

Hi there,

I would like to generate a random output from a set of list in an array.

For example, let x be an array in the data step.

x = {apple, orange, pear}.

I would like to create a new variable to generate a random output from the list above.

How do I do that?

Thanks,

Tan

Welcome to the SAS Community 🙂

You can do something like this

data test;
   array MyArray{3} $ _temporary_ ("Apple", "Orange", "Pear");
   RandomFruit=MyArray[rand('integer', 1, dim(MyArray))];
run;

Do they have teh same probability of occurring? If so, see @PeterClemmensen's solution. If not, you can modify it with the TABLE option on the RAND() function.
