Data array

Wintrack provides storage space for 100 data arrays, temporary internal data structures that you use while processing the statements of a custom variable definition file in order to analyze case documents. Each element of a data array represents a trial of the case currently being analyzed. Depending on the analysis in course, it may hold values such as the average swim speed during the trial or the time spent in a given quadrant, etc. Data arrays are created by collapsing the active data matrix using the Collapse statement., or by collecting data from a data surface using the Collect statement. They may serve in turn as data source for creating trial variables using the Tabulate statement, for extracting data values using the Extract statement, or as criteria for de/selecting cells in a data matrix using the Include and Exclude statements.
