• Stata has a built-in command called “reshape” to change the data structure, but SAS needs to use array to do so. For example, the first time through the DO loop the statement is understood by SAS to be: howFAR(1) = howFar(1) * 1.609 ; The second time through the DO loop the statement is understood by SAS to be: howFAR(2) = howFar(2) * 1.609 ; Output produced by Step 4 (Print the dataset distancesInKM to see the distances as they have been The following SAS code will “switch” the data to long format and store it as a temporary file. The wide file is one record per person; the long is 4 records per person. The SAS program was downloaded with the files. Widetolong.SAS Data long; Set mylib.wide; Array wt{4} weight1 weight2 weight3 weight4; Do i = 1 to 4; weight = wt{i}; Output; End; 2014-09-21 Arrays in the SAS language are different from arrays in many other languages.

This paper compares three methods of long-to-wide conversion, two common (PROC TRANSPOSE and arrays) and one not commonly used (PROC SUMMARY). It also shows how PROC SQL can be used to find information Reshaping from long to wide in SAS can often be done using arrays or proc transpose. See our SAS arrays seminar and our reshaping in SAS learning module for details on these.

First of all, the syntax for constructing arrays, especially for multi-dimensional arrays, is complicated; there are way too many rules.

During the first iteration, the SAS statement uses Rev1 and Exp1 and uses them to calculate the net income and assign that value to Net_Inc1. SAS starts with this statement: net_inc[i] = revenue[i] - exp[i]; represents a wide file that we want to make even wider. As such, with PROC TRANSPOSE, we first have to use the procedure to transform the wide file into a longer file, and then use PROC TRANSPOSE, again, to transform the longer file into the ultimately desired width.

As with long dataset to wide dataset transformations, the BY statement can also be used to with wide to long dataset transformations to expand transposed variables into by groups.

rows to columns. Example 1: The PROC TRANSPOSE Options. In this first example, we will reshape the data shown below. As with long dataset to wide dataset transformations, the BY statement can also be used to with wide to long dataset transformations to expand transposed variables into by groups. The SASHELP.APPLIANC dataset contains sales data for 24 appliances across 156 different sales cycles. Do you get data that are “short and wide”?

Example 1: The PROC TRANSPOSE Options. In this first example, we will reshape the data shown below. • There are two types of data structure: wide and long. The wide format means one-record-per- person, and the long format means multiple-record-per-person.

Example 1: The PROC TRANSPOSE Options. In this first example, we will reshape the data shown below.

can start at any numeric value. The following array also has a dimension of 3, however its index starts at 0, and can take on a maximum value of 2. array list {0:2} aa bb cc; When the number of array elements is unknown, an asterisk can be used to cause SAS to determine the dimension for you.

It's a very handy technique to solve this challenge. Otherwise, it would be a very time consuming task. The following SAS code will “switch” the data to long format and store it as a temporary file. The wide file is one record per person; the long is 4 records per person. The SAS program was downloaded with the files.
