The array contains ten variables: five temperature measures (t1 through t5) from two cities (c1 and c2): array temprg{2,5} c1t1-c1t5 c2t1-c2t5; SAS places variables into a multidimensional array by filling all rows in order, beginning at the upper-left corner of the array (known as row-major order). work because SAS can not determine the array subscripts by counting the number of elements in multidimensional or _TEMPORARY_ arrays. A SAS ARRAY is a set of variables of the same type, called “elements” of the arry, that you want to perform the same operation on. It provides a simple, appropriate way to process a group of variables in a SAS DATA step. Let's say that you have an ARRAY statement like this in your program: ARRAY ARR (5) v1 v2 v3 v4 v5; or ARRAY LL (4) $ lucy ricky fred ethel; Examples. One solution to this problem is to transpose the data from long to wide; then we can use the array to do the comparisons very easily. array mult{5,10,2} mult1-mult100; Both methods return the same value for DIM, as shown in the table that follows the SAS code example. For example, a two-dimensional array provides row and column arrangement of array elements. Example 2: Multidimensional Array. Both methods return the same value for DIM, as shown in the table that follows the SAS code example. An array name is assigned to the set of variables. The goal is to compare each observation with the previous and the next observation. The HBOUND function returns the upper bound of a one-dimensional array or the upper bound of a specified dimension of a multidimensional array. So unless you defined your arrays as temporary, your variables are already stored in a SAS dataset, as variables. Then the array name is reference in other DATA step programming to do an operation on the entire set of variables in the SAS Arrays : Introduction. Dear all, I am using SAS 9.3 and I would like to fill a two-dimensional array from a current table of data in a data step (I do not have proc IML and I want to learn how to proceed using arrays). SAS places variables into a multidimensional array by filling all rows in order, beginning at the upper left corner of the array (known as row-major order). ARRAY SIMPLE (24) L1R1C1 L1R1C2 L1R1C3 L1R1C4 Array array-name {number-of-elements} list-of-variables; Note: You can use [ ] or { } or ( ) for defining number of elements in the ARRAY statement. You can think of the variables as having the following This example shows two ways of specifying the DIM function for multidimensional arrays. SAS places variables into a two-dimensional array by filling all rows in order, beginning at the upper left corner of the array (known as row-major order). This example shows two ways of specifying the DIM function for multidimensional arrays. Use HBOUND in array processing to avoid changing the upper bound of an iterative DO group each time you change the bounds of the array. Syntax. A more subtle usage of arrays. A SAS Array is a convenient way to create a reference to a group of variables. Note: If you are going to do exactly the same thing to all the array elements you can define the array as a one dimensional array and process inside a single loop.
