SAS Tutorial: Transposing Data
This tutorial topic illustrates procdures for transposing data, i.e., converting observations into variables or variables into observations. This concept is illustrated in figure 1. The observation to variable transposition is represented by the transition from la to lb. Variables to observations is represented by 1b to 1a. The transition from 1a to 1c and vice-versa requires transposing subsets of the data separately. The data structures illustrated by la and 1c will be referred to here as linear data sets and rectangular data sets, respectively.
